Thermoelectric Ag-Bi-Sb-Te alloys with the general formula AgxBi0.5Sb1.5-xTe3 (x =0.05∼0.4) were prepared by spark plasma sintering and their electrical properties were examined. The alloys exhibit large electrical conductivities in the whole temperature range, which are approximate 11.0 and 3.5 times those of pseudo-binary Bi0.5Sb1.5Te3 alloy at room temperature and 558K, respectively. The highest power factor value of 1.80×10-3 (W.K-2.m-1) is obtained for the material (x = 0.1) at the temperature of 412K, being about 2.4 times that of pseudo-binary alloy Bi0.5Sb1.5Te3 at the corresponding temperature.

The paper presents the results of studies of the effect of heat treatment regimes on changes in the structure and properties of steel-copper alloy pseudo-alloys obtained by infiltration. It is shown that, depending on the composition and initial density of the steel skeleton, the strength of the material increases by 1.3–1.8 times, the hardening effect is realized when the carbon content in the steel skeleton is 0.3–1.5 % and is achieved due to changes in the structure and phase composition of the steel base and copper phase. It has been established that during heating for quenching and during tempering, redistribution of carbon occurs in the iron phase, which is more pronounced in the frame of the pseudo-alloy made of medium-carbon steel. The formation of a “crust” structure in the grains of the skeleton is noted, while in the skeleton made of medium-carbon steel this occurs at a tempering temperature of 200 °C, in low-carbon steel – at a temperature of 500–650 °C. In a high-carbon steel skeleton, carbon stratification in the grain body is less pronounced. An increase in the strength of pseudo-alloys at tempering temperatures of 500–650 °C is associated with the formation of the α′-phase, the precipitation of the Fe3C carbide phase and the metastable Fe2C phase in the iron phase, as well as the precipitation of dispersed phases Fe4Cu3, Fe4Cu3, η-Cu6Sn5 and δ-Cu3Sn8 in the copper phase. Due to the precipitation of phases, the microhardness of the infiltrate in the form of copper in pseudo-alloys after tempering at 550 °C increased from 820–880 to 950–980 MPa, in the form of tin bronze – from 1450 to 1750 MPa. The use of heat treatment leads to an increase not only in the strength, but also in the tribotechnical properties of the pseudo-alloy: the friction coefficient of the pseudo-alloy with a frame of 80 % density made of FeC0.8 steel decreases to 0.008–0.009, the seizure pressure doubles and the wear resistance increases by more than 2.5 times.

The mixing properties of liquid Al–Au alloys with respect to the concentration of each constituent is determined using a method based on hard sphere system and pseudo-potential perturbation. These models were used to get relevant information on mixing properties of the Al–Au alloys like the Gibbs energy and the entropy of mixing. The concentration fluctuations, chemical short range order for the hard sphere mixture (quasi-lattice theory) and the activity are calculated to know the extent of order in the liquid alloys. The results revealed that there is a degree of ordering in liquid Al–Au alloy (hetero-coordinated).

Abstract Fatigue is due to accumulation of undesired defects by repeated loading cycles. Classical fatigue leads to the formation of localised strain and nucleation and propagation of cracks. In shape memory alloys, there are additional fatigue phenomena: 1. Thermal cycling plays a role mainly for the two-way effect; 2. Pseudo-elastic fatigue can precede classical fatigue. Pseudo-elastic fatigue consists in deterioration of the hysteresis and consequently the loss of damping ability and transformability. It is related to the localisation of the martensitic transformation reaction.

Abstract A systematic high-resolution electron microscopy study of a special type of two-dimensional defects, phason planes, has been carried out in the structurally complex metallic alloys of Al –Pd –Mn and Al –Ni –Rh. The structural characteristics of the phason planes in these two alloys consist of pentagon-banana pairs of polygons but with a different arrangement. Located on the vertex of the polygons are pseudo-Mackay atomic clusters. The detailed atomic structures of the phason planes in both ξ′- and ξ-phases of the two alloys have been determined by means of high-resolution electron microscopy and theoretical simulations. The possible ways of displacement of the phason planes in the complex alloys are discussed.

Residence permits pseudo-alloys are used for the manufacture of cylinder parts, bushings, complex-shaped blanks with curved surfaces: gyroscope rotors, inertial masses, erosion-resistant electrodes, funnel for cumulative charges, biological protection from gamma radiation. Recycling of tungsten pseudo-alloys residence permit is relevant and necessary due to the shortage of tungsten. A promising method of processing waste into fine powders is the method of electroerosive dispersion (EED) that we have chosen. The purpose of the work is to study the morphology and elemental composition of the powder of the VNZh-95 pseudo-alloy obtained by electroerosive dispersion in kerosene. In order to process the waste of the W-Ni-Fe alloy into powder, we used waste in the form of chips from the core of the VNZh-95 pseudo-alloy (Ni ̶ 3.2-3.7, Fe ̶ 1.5-2.0, W ̶ the rest). Kerosene is used as a working fluid. The EED process was carried out on the installation for obtaining powders from conductive materials (patent for the invention of the Russian Federation No. 2449859). The process was carried out at a voltage on the electrodes of 100 ... 110 V, the capacitance of the discharge capacitors 50 μF and a pulse repetition rate of 120 ... 130 Hz. The microstructure of the samples (along the transverse section) was studied using a Quanta 200 3D electron-ion scanning microscope. The powder obtained by the EED method for waste of VNZh-95 alloy in kerosene consists of particles of regular spherical shape (or elliptical) and irregular shape (conglomerates). Microanalysis of particles of electroerosive powder of pseudo-alloy VNZh-95 was carried out using an EDAX energy-dispersive x-ray analyzer built into the Quanta 200 3D scanning electron microscope. As a result of studying the elemental composition of the VNZh-95 pseudo-alloy powder obtained by EED in kerosene, it was found that the main elements are tungsten, nickel, iron, carbon and oxygen.

Activity of tin in liquid Sn-Ag-Bi alloys was derived by EMF measurement of galvanic cell with fused salts electrolyte in the temperature range of 700 to 900K in the whole composition range. Activity of tin at 900K shows very small positive deviation from Raoult’s low for Sn-Bi alloys. Activity of ternary alloys was measured along three pseudo binary systems of Sn-(Ag,Bi) (where xAg/xBi =1/3,1/1 and 3/1). Its concentration dependence is very complex. From the iso-activity curves in the ternary system excess free energy of mixing is derived using Darken’s method for Gibbs-Duhem equation

High entropy alloys (HEAs) generally exhibit either high resistance to deformation or high toughness due to the presence of body-centered or face-centered cubic structure, respectively. To overcome these limitations, new high entropy alloys have been developed in the present study. This investigation aims to synthesis and characterization of novel CoCrFeNi3Si, CoCrFe2Ni2Si, and Co2CrFeNi2Si high entropy alloys. The mechanical alloying route is used to synthesize these alloys. Grinding was carried out to 20h and X-ray diffraction (XRD) analysis was done at different time intervals of grinding. The face-centered cubic structure along with the intermetallic compound of Ni-Si was observed after 20h of grinding. Furthermore, a pseudo binary strategy based on the valence electron concentration and mixing enthalpy is also employed to design the high entropy alloys considered in the present study. Carefully analysis of the XRD pattern indicates that from 5 to 20h of mechanical alloying there is a decrement in the initial peaks of elements observed.

Spark plasma sintering (SPS) is widely used for the consolidation of different materials. Copper-based pseudo alloys have found a variety of applications including as electrodes in vacuum interrupters of high-voltage electric circuits. How does the kinetics of SPS consolidation for such alloys depend on the heating rate? Do SPS kinetics depend on the microstructure of the media to be sintered? These questions were addressed by the investigation of SPS kinetics in the heating rate range of 0.1 to 50 K/s. The latter conditions were achieved through flash spark plasma sintering (FSPS). We also compared the sintering kinetics for the conventional copper–chromium mixture and for the mechanically induced copper/chromium nanostructured particles. It was shown that, under FSPS conditions, the observed maximum consolidation rates were 20–30 times higher than that for conventional SPS with a heating rate of 100 K/min. Under the investigated conditions, the sintering rate for mechanically induced composite Cu/Cr particles was 2–4 times higher compared to the conventional Cu + Cr mixtures. The apparent sintering activation energy for the Cu/Cr powder was twice less than that for Cu–Cr mixture. It was concluded that the FSPS of nanostructured powders is an efficient approach for the fabrication of pseudo-alloys.

Purpose: In order to clarify whether amorphization occurs in the pseudo-binary C14 HfNi0.6Al1.4 Laves phase a detailed investigation of the effect of hydrogen treatment on it phase-structural state has been studied. This type of compounds is of interest due to their high possibility to hydrogen absorption as Laves phase structures and as Hf-Ni alloys. Design/methodology/approach: We used a combination of hydrogen treatment and grinding methods for studying of the processes of controlled structure formation. High temperature transformations of the HfNi0.6Al1.4 alloy were pointed out by means of XRD analysis. Findings: By combination of two amorphization methods and high temperature measurements we have observed a phase structural transformation of the HfNi0.6Al1.4 alloy, which could be presented as: HfNi0.6Al1.4(cryst.) + H2 ® HfNi0.6Al1.4 (nanocryst.) + HfNi0.6Al1.4 (amorphous) + H2 ® HfH2 (amorphous) + AlH3 (amorphous) + Ni. Ferromagnetic- like properties of the pseudo-binary HfNi0.6Al1.4 Laves phase was found. Research limitations/implications: Complex research of HfNi0.6Al1.4 alloy revealed various structure features depending on phase content, thermodynamic parameters and conditions of hydrogen treatment. Obtained results suppose that further studies of structure and physical properties of Hf-Ni-Al alloys will allow to find the methods to control the producing of materials with desired properties. Practical implications: Using of hydrogen treatment is effective to produce Al-based alloys with improved magnetic properties. Originality/value: Treatment in hydrogen atmosphere allows improving the glass-forming ability in Hf-Ni-Al alloys.
