Abstract In this review we are considered systematically the phenomenon of deformation-induced phase transformations from crystalline intermetallic compounds and complex phases to amorphous state and vice versa phase transformations from amorphous state to crystalline one upon severe plastic deformation at different temperatures. The nature and structural features of these transitions essentially for high pressure torsion deformation are analyzed in the frame of basic principles of nonequilibrium thermodynamics. The effects of phase cycling and a stationary amorphous - nanocrystalline state formation at significant deformations is discussed in details.

Carter, Karen E. "Grenville orogenic affinities in the Red Mountain area, Llano Uplift, Texas." Canadian Journal of Earth Sciences 26, no. 6 (June 1, 1989): 1124–35. http://dx.doi.org/10.1139/e89-096.
The Red Mountain area in the southeast corner of the Llano Uplift contains evidence of a Grenville-age, polyphase, non-coaxial deformational history. Four synmetamorphic deformational phases affected the Precambrian Click Formation of the Packsaddle Group, and a single shear-related deformation is observed in the Big Branch and Red Mountain gneisses. The first phase of deformation produced tight folds with an axial–planar metamorphic foliation. The second, and most intense, pervasive deformational phase produced the regional metamorphic layering, isoclinal folds, transposition of bedding, and mylonitic textures in the gneisses. The third deformation is characterized by tight to isoclinal, north-verging folds with an axial–planar differentiation crenulation cleavage. The fourth phase of deformation resulted in a north-northwest-trending differentiation crenulation cleavage that is axial–planar to small east-northeast-verging folds. The growth of cordierite over all foliations indicates that low-pressure metamorphism postdated all four deformational phases.The second deformation had begun at the latest by 1167 ± 2 Ma, the age of metamorphism of the gneisses, and before the intrusion of melarhyolite dikes dated at 1080 ± 30 Ma. Thus, the orogenic event(s) responsible for the complex deformational and metamorphic history is Grenvillian in age.

Research on multipass plastic deformation of 7A04 ultra-high strength aluminium alloy by isothermal compression experiments on the 6300KN extrusion press. Experiment results show that elongation reaches its maximal value 9.25% after the first deformation. It is obvious that fibrous tissues appeared along the metal flow direction in the deformed 7A04 ultra-high aluminium alloy, with heterogeneous distribution of precipitated η (MgZn2) phase in the matrix, which results in lower strength (Rm=335MPa, Re=212.5MPa). As the times of deformation increases, precipitated phases grow gradually and the plasticity of alloys decreases dramatically, which reaches its minimal value 5.17% after the fourth deformation. With η(MgZn2) phase disperses gradually, the strength of the alloy increases gradually, and reaches its maximal value 386.7MPa after the fourth deformations. It is proved that 7A04 high-strength aluminium alloy has better synthetic mechanical properties after four times deformation.

Abstract The vertical seismic deformation of the Palu earthquake magnitude of 7.4 on the Richter Scale, which occurred on September 28, 2018, has been analyzed using InaCORS (Indonesian Continuously Operating Reference Stations) stations. The stations used are CBAL, PALP, CTOL, CMLI, CPAL, and CBIT. The analysis was conducted using GAMIT, GLBOK, and GMT software. The analysis focused on the period of 100 days, starting from August 6, 2018 (DoY 218) to November 28, 2018 (DoY 318), encompassing the preseismic, coseismic, and post-seismic phases. During the preseismic phase (DoY 218-270), the InaCORS stations experienced a slight deformation ranging from -10.9353 mm to 6.5525 mm. Tectonic manifestations influenced the direction of movement in Sulawesi. The deformation significantly increased in the coseismic phase (DoY 271-272). The InaCORS stations experienced deformations ranging from -169.8 mm to 8.755 mm, which differed in the direction from the preseismic phase. The stations in the northern region predominantly moved towards the north, while those in the southern region moved towards the south. During the post-seismic phase (DoY 273-318), the movement of the InaCORS stations followed the direction of deformation observed in the coseismic phase. However, the displacement was relatively smaller, ranging from 11.5909 mm to 17.23733 mm.

The inherent unknown deformations of inverse synthetic aperture radar (ISAR) images, such as translation, scaling, and rotation, pose great challenges to space target classification. To achieve high-precision classification for ISAR images, a deformation-robust ISAR image classification network using contrastive learning (CL), i.e., CLISAR-Net, is proposed for deformation ISAR image classification. Unlike traditional supervised learning methods, CLISAR-Net develops a new unsupervised pretraining phase, which means that the method uses a two-phase training strategy to achieve classification. In the unsupervised pretraining phase, combined with data augmentation, positive and negative sample pairs are constructed using unlabeled ISAR images, and then the encoder is trained to learn discriminative deep representations of deformation ISAR images by means of CL. In the fine-tuning phase, based on the deep representations obtained from pretraining, a classifier is fine-tuned using a small number of labeled ISAR images, and finally, the deformation ISAR image classification is realized. In the experimental analysis, CLISAR-Net achieves higher classification accuracy than supervised learning methods for unknown scaled, rotated, and combined deformations. It implies that CLISAR-Net learned more robust deep features of deformation ISAR images through CL, which ensures the performance of the subsequent classification.

This article presents the influence of severe plastic deformation by hydrostatic extrusion (HE) on the thermal and structural properties of polyamide 6 (PA6). During the hydrostatic extrusion process, a fibrous structure oriented along the extrusion direction is formed, which was visualized during microscopic observations. The degree of crystallinity was analyzed by differential scanning calorimetry (DSC). Wide-angle X-ray scattering diffraction (WAXS) analysis was used to partially characterize the PA6 structure after the HE process. The contents of various forms of the crystalline phase in PA6 samples before and after the HE process were analyzed in fragments of spectroscopy in infrared (FTIR). The favorable properties of PA6 after the HE process were obtained after deformation under conditions generating an adiabatic temperature higher than the glass transition temperature and lower than the temperature of the onset of melting of the crystalline phase. Thermal analysis using DSC allowed us to conclude that in the PA6 after the HE process generating deformations in the range of 0.68–1.56, the proportion of the crystalline phase α increases in PA6. As the deformation increases in the HE process, the crystalline phase proportion increases by 12% compared to the initial material (before HE). The glass transition temperature of PA6 is ca. 50.6 °C, reduced for the sample after the HE process at a small deformation of 0.68 (PA6_0.68) to ca. 44.2 °C. For other samples, Tg is ca. 53.2–53.5 °C. As a result of the analysis of WAXS diffractograms of PA6 samples after various deformations in the HE process, the presence of typical peaks of phases α1 and α2 and γ was observed. The results of the FTIR spectroscopic analysis confirm these observations that as the deformation increases, the proportion of the crystalline phase α increases.

Ryś, Janusz, and Anna Zielińska-Lipiec. "Structural Aspects of Ferrite and Austenite Co-Deformation in Duplex Stainless Steel." Solid State Phenomena 203-204 (June 2013): 28–33. http://dx.doi.org/10.4028/www.scientific.net/ssp.203-204.28.
The present research is a part of project dealing with structural aspects of ferrite and austenite co-deformation in duplex stainless steels. The examination concerned a development of ferrite and austenite microstructures, major deformation mechanisms operating in both phases and texture formation upon cold-rolling of a model duplex type steel. The investigations showed that the band-like morphology of two-phase structure formed upon processing together with specific starting textures obtained after a preliminary thermo-mechanical treatment exerted significant influence on texture and microstructure development in both constituent phases. Microstructure and texture evolution in examined duplex steel significantly differed from those in one-phase steels. These differences resulted first of all from the role of the phase boundaries acting as the barriers for dislocation movement and affecting the processes of strain localization at higher deformations.
Hall, Ernest L., and James D. Livingston. "Deformation modes in Laves phase intermetallics." Proceedings, annual meeting, Electron Microscopy Society of America 47 (August 6, 1989): 318–19. http://dx.doi.org/10.1017/s0424820100153567.
There is at present a large amount of interest in the mechanical behavior of intermetallic alloys, and one of the largest classes of these alloys are the Laves phases. There are three basic types of Laves phases: cubic (C15), hexagonal (C14), and dihexagonal (C36), with stacking sequences on the close-packed planes of ABCABC..., ABAB..., and ABAC..., respectively, where each capital letter represents an interpenetrating four-atomic-layer unit. This structural complexity gives rise to a special mode of deformation for Laves phases, called synchroshear, which requires the cooperative movement of adjacent layers in different directions. Very little work has been done to date on the deformation modes in Laves phases because of the inherent brittleness of these materials at room temperature. However, through alloying it is possible to obtain mixtures of the various Laves phase types, and to affect such properties as stacking fault energy, and thus opportunities may exist for increasing ductility. In this study, the deformation microstructures of different Laves phase types were explored.
Ground-based synthetic aperture radar (GB-SAR) uses active microwave remote-sensing observation mode to achieve two-dimensional deformation measurement and deformation trend extraction, which shows great prospects in the field of deformation monitoring. However, in the process of GB-SAR deformation monitoring, the disturbances caused by atmospheric effect cannot be neglected, and the atmospheric phases will seriously affect the precision of deformation monitoring. In discontinuous GB-SAR deformation monitoring mode, the atmospheric phases are particularly affected by changes of time and space, so the traditional models of atmospheric phase correction are no longer applicable. In this paper, the interferometric phase signal model considering atmospheric phase is first established. Then, the time- and space-varying characteristics of the atmospheric phase are analyzed, and a novel time- and space-varying atmospheric phase correction algorithm, based on coherent scatterers analysis, is proposed. Finally, slope deformation monitoring experiments are carried out to verify the validity and robustness of the proposed algorithm.

Two-phase Ti6246 alloy is a light weight material exhibiting very high strength at higher temperatures compared to the commonly used Ti64 alloy. This particular alloy is used at the later stages of compressor discs within the aero engines. However, compressor discs undergo a number of cyclic stresses, which could eventually lead to fatigue failure. In order to optimize the microstructure for design and lifing models, an improved understanding of the localised deformation mechanisms is crucial, particularly at the surface, as cracks can be initiated leading to failure and in turn affect the life expectancy of the component. Two-phase alloys in use have very complex lamellar microstructures comprising of a mixture of coarse and fine phases and their role in deformation can be very complex and difficult to understand. The focus of this study was particularly based on the importance of the beta phase in strengthening two-phase microstructures. Therefore, this study has been simplified to compare model lamellar microstructures, which have particular sizes of beta phase in between alpha lamellae. Digital Image Correlation along with high resolution imaging was used to develop a detailed understanding of the localised deformation in these microstructures. Widening the beta phase in-between alpha lamellae caused a more homogenous deformation, while ageing the beta phase with fine secondary alpha strengthened the microstructure. However, all microstructures showed that the single continuous alpha layer at beta grain boundaries depicted the highest amount of deformation, which can be detrimental for the life of the component. The behaviour of slip at the α/β interface not only depended on the size of the phases but also depended on the neighbouring crystallographic orientations and the relationship of the two phases, specifically the alignment of the close packed slip directions. Strain maps of these microstructures were subsequently related to corresponding Schmid factor maps and crystal plasticity models to improve this understanding.

The tensile experiment for nanomaterials in a transmission electron microscope (TEM) has become a very important tool to study the atomic deformation of material at nanoscale. An enormous amount of effort has been spent to perform the tensile experiments on nanomaterials. They revealed new discoveries that have never been observed in bulk materials and eventually lead to further applications. In this thesis, experimental reports of tensile test on gold nanoribbons in TEM were reported. The gold nanoribbons have 4H structure but the FCC structure could coexist in some areas. Gold nanoparticles have been studied intensively in the past decades due to their extraordinary properties and promising applications. The rise of chemical syntheses technology has stimulated further exploration of gold nanoparticles in recent years. The wet chemical technique has successfully created more closed-packing structures that have never been discovered before, including 4H gold nanoribbons. Even though the latest syntheses techniques have created many interesting structures, the investigation of their mechanical properties seems to be very difficult to perform. The tensile experiment on gold nanoribbons has never been performed. This thesis reports the first investigation of the mechanical properties of gold nanoribbons by using tensile test in TEM. Phase transformation from 4H to FCC or vice versa were observed. The dislocation in the structures leads to the phase transformation. Furthermore, necking has also been observed during tensile test, particularly in the FCC structure which eventually lead to ductile fracture. However, necking was also observed in 4H structure. In addition to this, coalescence between two nanoribbons was also observed during tensile.

Defects, i.e. hot tears, macrosegragation, and pores, formed in metal castings are a result of stresses and strains in the solid-liquid mushy zone. Numerical simulation of solidification of deforming dendrite crystal promises to improve insight into the mechanical behavior of mushy zones under an applied load. The primary goal of this thesis is to develop numerical methodologies for performing solidification simulation of deforming dendrites. Such simulation encounters difficulties associated with the interface dynamics due to phase change or interaction among the dendrites, and large visco-plastic deformation applied to them. Phase-field simulation of dendritic solidification is promising for the treatment of the complex interface dynamics. Free energy based formulation allows the model to incorporate bridging and wetting phenomena occurring at grain boundaries through an extra energy term which arises from a mismatch of the crystallographic orientation. The particle method would be attractive to handle large inelastic deformation without suffering mesh entanglement. In order to investigate the effect of solid deformations on the evolving microstructure, the material point method with elasto-visco-plasticity constitutive model is developed to couple to a phase-field model of solidification. The changes in the crystallographic orientation of a growing dendrite crystal due to solid deformation are carefully accounted for through the coupling methodology. The developed numerical framework is applicable to the simulation for single and multiple crystals, and is capable of handling complex morphological change. The wide variety of validations and practical problems solved in this thesis demonstrates the capability of investigating deformation behavior of growing crystals.

The effect of high temperature, high strain rate deformation on the evolution of second phase particles in commercial aluminium alloys has been investigated. Three model alloys provided by Novelis have been examined, and the evolution of particles during deformation has been examined for the alloy that most closely resembles the composition of alloys used in commercial applications. The effect of deformation mechanisms was expected to be an enhancement of diffusion controlled processes; therefore the first part of the work was to develop a heat treatment that would produce a fine distribution of dispersoid particles. This heat treatment was then used to prepare material for torsion testing, at strain rates similar to those found during the hot rolling stage of commercial production. Testing was performed at both the end of heat treatment temperature, to remove thermal effects, and at a lower temperature which more closely represents the temperature during commercial rolling. Material was examined by optical microscopy, FEGSEM and TEM and the particle populations were characterised by backscattered FEGSEM imaging and image analysis. This demonstrated that the disperoid particle population develops in multiple ways. Along with the enhancement of coarsening there is a significant shape change to the dispersoid particles, suggesting a change in the character of their interface. It has also been demonstrated that there is nucleation of new particles, despite a long prior hold time, in material deformed at the same temperature as the heat treatment. Material deformed at lower temperatures also demonstrated a larger increase in the volume fraction of dispersoid than material with the same thermal history. A constitutive model for diffusion enhancement and a model for particle evolution have been combined to simulate the effects of thermomechanical processing on the particle population.

This thesis presents a systematic study on evolutions of microstructure, microhardness and superplasticity of a Pb-62% Sn alloy processed by both equal-channel angler pressing (ECAP) and high-pressure torsion (HPT) and the subsequent self-annealing process at room temperature (RT). The Pb-Sn alloy exhibits characteristics with significant grain refinement after processing by ECAP and HPT but with a reduction in the hardness values by comparison with the initial as-cast condition. For HPT processing, it is shown that there are generally smaller grains at the edges of the discs by comparison with the disc centres. The hardness results are different from those generally reported for conventional single-phase materials where a hardening trend was commonly observed after HPT processing. The significance of this difference is examined. The microstructures of the alloy after HPT were repeatedly investigated during the course of self-annealing by scanning electron microscopy (SEM), electron backscatter diffraction (EBSD) and scanning electron microscopy (TEM). A significant grain growth combined with increase of microhardness was observed. It was demonstrated that there was a large fraction of twin boundaries with a twin relationship of 62.8°<100> in the microstructure for the as-cast condition. Owing to the presence of high pressure, the mobility of Ʃ21 boundaries at 71° was greatly favoured during processing by HPT. But the mobility of the dislocation-twin boundary near 62.8°<100> was favoured during self-annealing at RT once the high pressure was removed. The HPT processing significantly increased the solubility of Sn in Pb phase. This supersaturated state of Sn in Pb is, however, not stable at RT during self-annealing and therefore a decomposition of Sn from Pb-rich phase was observed after 16 days of storage. Lattice diffusion should be considerable as the main mechanism for the decomposition. Moreover, abnormal grain growth was observed to be greatly favoured during self-annealing when the introduced strain was relatively low, i.e. 2 passes by ECAP and the centre region of a HPT-processed disc after one turn. Consequently, a series of HPT-processed samples with different storage time was tested in tension at RT and at 1.0 × 10-4 - 1.0 × 10-1 s-1. The results demonstrated that, despite the storage time, all processed alloy exhibited excellent RT superplasticity at 1.0 × 10-4 s-1 and the highest elongation of 630% was recorded in the processed alloy after storage for 4 days at RT. The detailed investigation showed, due to the high strain rate sensitivity of the processed alloy, a transition strain rate of ~1.0 × 10-2 s-1 was observed in which stain softening with ductile behaviour is apparent due to active GBS below the transition point but high strength is observed because of grain boundary strengthening above the transition during plastic deformation at RT in the Pb-Sn alloy after HPT. Nanoindentation tests were then performed applying both indentation depth-time (h-t) relationship at holding stage and the hardness, H, at various loading rates to explore the evolution of strain rate sensitivity (SRS), m. The results obtained by both tensile test and nanoindentation show that the relatively fast self-annealing of the HPT-processed Pb-62% Sn eutectic alloy is occupying by an unambiguous changing-tendency of strain rate sensitivity. The results confirm the validity of using nanoindentation for measuring strain rate sensitivity.

This report describes the output of two phases of the research contract on �Effects of Operating Practice on SCC Crack Growth�, GRI-05/8668, submitted to PRCI in August 2002 (Phase I) and in July 2003 (Phase II). The objective of the first phase of the work was to identify, through literature survey, a correlation model that relates the crack growth rate in low-pH or in high-pH environments to the deformation rate of the line pipe steel. The objective of the second phase of the project was to experimentally validate the correlation model(s) identified in Phase I. The ultimate goal of this work is to define the critical loading condit ions necessary for SCC so that operating practices can be assessed for the purpose of eventual avoidance of SCC. It is also hoped that such a deformation-rate-based model can provide insight for understanding the transition between �active� and �inactive� (or dormant) states of the cracking that is often observed in laboratory SCC tests. Understanding the causes for dormancy of stress corrosion cracks and the mechanism(s) of crack reactivation has significant practical implications. Service life is extended if conditions of dormancy can be maintained and conditions of growth or reactivation can be avoided.

The research described in this report is focused on the dynamics of the brine strings utilized in solution-mined caverns. In Configuration 3, fluid enters the system from the top of the brine string and exits via the annulus between the brine string and the casing. In Configuration 4 the flows are inverted. An improved analytical model for stability of the brine string in Configuration 3 has been generated, and considerably better modelling for Configuration 4 achieved. Experiments in a bench-top sized system and CFD work were pursued partly to further improve the analytical models, and partly to explain some unexpected observations from a full-scale cavern, reported by Reitze in 2019. Note: Phase IV of this research was funded jointly by the Solution Mining Research Institute (SMRI) and Pipeline Research Council International (PRCI), and SMRI has published this same report with some formatting differences.

The objective of the Stress-Corrosion Cracking (SCC) Phase of the NG-18 program is to develop an understanding of the causes of external SCC and methods of controlling it on new and existing gas transmission pipelines. An overview of past and proposed NG-18 programs designed to address this objective is given in Figure 1 in the Introduction Section, where it can be seen that the research has been divided into two categories, SCC mitigation and life estimation. The research carried out in 1985 at BCD focused on several areas under these categories: (1) the development of resistant steels and surfaces, and (2) the development of a crack growth/life prediction model. In the former, three experimental tasks were carried out in 1985, deformation response behavior, grain boundary chemistry, and surface effects. In the latter, a preliminary investigation of slip related models for describing SCC was carried out. Accomplishments on these tasks are described below.

This report discusses the use of Synthetic Aperture Radar (SAR) satellites for monitoring above ground pipelines and buried pipeline Rights-Of-Way (ROWs) using Interferometric Synthetic Aperture Radar (InSAR) techniques. The main thrust of the research was to evaluate the suitability of above-ground pipeline support members as InSAR measurement points, and to adapt existing techniques to allow for precise monitoring of jacking and subsidence caused by permafrost degradation and dynamics. The study site at Prudhoe Bay, Alaska includes more than 60,000 horizontal pipeline supports. The known locations of supports were used to identify and isolate supports in the radar imagery, and the phase and intensity of supports were analyzed to determine their ability to provide reliable estimates of deformation. An additional component of this research was the comparison of two satellites operating at different frequencies, RADARSAT-2 operating at C-band and TerraSAR-X operating at X-band. One year of data was acquired with both sensors in similar acquisition geometries and resolutions, at 24-day intervals for RADARSAT-2 and 11-day intervals for TerraSAR-X. Recommendations are made on the choice of wavelength and concerning future work in this area. A list of technical requirements is also provided. The technologies for obtaining ground deformation estimates from natural targets, coherent targets and homogeneous and distributed targets are explained and supported by three operational case-studies in different environments. The work should provide above-ground pipeline operators working in permafrost areas with a clear view of the current state of research towards the operationalization of InSAR monitoring, but also of current operational capabilities in other pipeline applications, including ROW geohazard monitoring and monitoring of buried pipelines crossing Enhanced Oil Recovery (EOR) fields.
