Abstract:
Thin films of a ternary alloys between aluminum, manganese and copper (AlMnCu), prepared at low temperature, are reported in the present work. It is a study along two binary edges (Al100−xMnx and Al100−xCux (from literature)), the first almost along the entire range of concentrations, and two different cuts through the ternary system. The first cut begins at amorphous Al50Mn50 and adds Cu step by step (from literature). The second cut begins at amorphous Al60Cu40 and varies Al and Mn such that the Cu-content stays constant. There is a wide amorphous range, purely amorphous or with additional quasi-crystalline local features, and there are ranges where mixtures between amorphous and nano- or partially crystalline phases with a high content of lattice defects exist. The work exclusively deals with the development of the static structure and its thermal stability, as well as the development of its electronic transport properties. The ternary AlMnCu is a model for a deeper understanding of different scenarios of structure stabilization and their interaction, with consequences on the emergence of physical properties. The analysis focuses on self-organizing spherical-periodic, global resonance effects between two global subsystems of the alloy under consideration, the Fermi gas as one and the forming static structure of ions as the other. The global resonances are self organizing by i.e. an exchange of characteristic momenta and energy between the subsystems and trigger, besides a particular structure, particle-density anomalies and/or hybridization effects. The work shows strong evidence of a combined action of the particle-density anomalies with the effective valence of the atoms involved, in order to maintain the resonance condition under all circumstances. Whereas at high Al-content, additionally, local features of quasi-crystallinity arise, closer to pure Mn phase separations arise, causing mixtures of amorphous with nano-crystalline phases or crystals with a high content of lattice distortions. Reports on density anomalies, hybridization effects, and angular correlations, have been published quite often. In the present work, besides similar effects in a ternary system, first indications for phase separations and lattice defects as additional scenarios of stabilizing condensed matter are reported. The resonance, seen as spherical-periodic-order at short- and medium-range distances in real space, causes in reciprocal space a resonance maximum (analogous to a Bragg peak in crystals). Its location on the axis of the scattering vector is defined by the electron system and a pseudo-gap in the electronic density of states arise at the Fermi energy. The origin of the structural order and its thermal stability, the pseudo-gap at the Fermi energy, as well as the transport properties with its anomalies, all are attributed to the resonance. The spherically-periodic atomic order in an amorphous phase is analogous to the planar order in a crystal. The interatomic distances between the nearest neighboring shells at short- and medium range distances coincide with half the Fermi wavelength, also called Friedel-wavelength
In der vorliegenden Arbeit wird über bei niedriger Temperatur hergestellte dünne Schichten aus einem ternären Legierungssystem zwischen Aluminium, Mangan und Kupfer (AlMnCu) berichtet, über zwei binäre Randlegierungen (Al100−xMnx und Al100−xCux (aus der Literatur)) und über zwei verschiedene Schnitte durch den ternären Bereich. Ein Schnitt durch den ternären Bereich beginnt bei amorphem Al50Mn50 und fügt schrittweise Cu zur Legierung (aus der Literatur). Der zweite Schnitt beginnt bei amorphem Al60Cu40 und fügt schrittweise Al und Mn so zu, dass der Cu-Gehalt konstant bleibt. Es gibt amorphe Bereiche, teilweise mit weiteren lokal quasi-kristallinen zusätzlichen Merkmalen, sowie Bereiche, in denen Mischungen aus amorphen mit nano oder teilkristallinen Phasen auftreten. Die Arbeit behandelt die Entwicklung der statischen Struktur und deren thermische Stabilität, sowie die Entwicklung elektronischer Transporteigenschaften. Das ternäre AlMnCu ist ein Modellsystem für ein tieferes Verständnis der verschiedenen Szenarien struktureller Stabilisierung und deren Interaktion, mit Auswirkungen auf ein tieferes Verständnis der mit der Struktur sich entwicklenden physikalischen Eigenschaften. Die Analyse konzentriert sich auf sich selbstorganisierende sphärisch-periodische, globale Resonanzeffekte zwischen zwei globalen Untersystemen des gewählten Materialsystems, der Fermi-Kugel als einem und der sich bildenden statischen Struktur der Ionen als dem anderen. Die globalen Resonanzen bilden sich u.a. durch einen Austausch von charakteristischen Impulsen und Energie zwischen den Untersystemen, die neben einer bestimmten Struktur zunächst auch Teilchendichteanomalien und/oder Hybridisierungseffekte erzeugen. Die vorliegende Arbeit zeigt dabei starke Anzeichen für eine kombinierte Wirkung dieser Effekte um die Resonanzbedingung unter allen Umständen beizubehalten. Bei hohen Al-Anteilen treten zusätzlich lokale Merkmale von quasi-Kristallinität, mit 5-facher Winkelkorrelation auf, um auch diesen Bereich strukturell zu stabilisieren. Bei hohen Mn-Anteilen sind es lokale Phasentrennung in amorphe und nano-kristalline Phasen oder hohe Anteile von Gitterdeffekten, die zusätzlich auftreten. Über Dichteanomalien, Hybridisierungseffekte und Winkelkorrelationen wurde in der Vergangenheit bereits mehrfach berichtet. In der vorliegenden Arbeit sind es, neben der modellhaften Behandlung dieser im ternären System, die Hinweise zu Phasentrennung und Gitterdeffekten als zusätzliche Szenarien zur Stabilisierung kondensierter Materie, über die erstmalig berichtet wird. Die auf dem Austausch von Impuls beruhende Resonanz, als sphärisch-periodische-Ordnung im nahen und mittleren Abstandsbereich des Ortsraumes zu sehen, verursacht im reziproken Raum ein Resonanzmaximum (analog zu einem Bragg-peak in kristallinen Systemen), dessen Lage auf der Achse der Streuvektoren vom Elektronensystem definiert wird, und eine Pseudolücke in der elektronischen Zustandsdichte der Elektronen an der Fermi-Energie. Letztendlich werden die Entstehung der strukturellen Ordnung selbst, ihre thermische Stabilität, als auch die Transporteigenschaften mit ihren Anomalien auf diese Pseudolücke und demzufolge auf die Resonanz zurückgeführt. Die sphärisch-periodische Ordnung der Atome in einer amorphen Phase ist analog zur planaren Ordnung in einem Kristall. Die Atomabstände zwischen den Nächstnachbarschalen im mittleren, aber auch nahen Abstandsbereich, stimmen über große Distanzen mit der halben Fermi-Wellenlänge überein, die man auch als Friedel-Wellenlänge bezeichnet

Tantalum is a refractory material, and copper and tantalum are immiscible, Cu-Ta pseudoalloy is likely to be a noble material for the high-temperature applications. In this study, Cu-Ta pseudoalloy films are prepared by R.F. magnetron sputter deposition technique. With careful control of processing conditions, the tantalum concentration in Cu-Ta films can be up to 14.9 at.% by sputter deposition. As Cu and Ta are mutually immiscible, nonequilbrium supersaturated solid solutions of Ta in Cu with nanocrystalline microstructures are observed in as-deposited Cu-Ta films. Variation in lattice parameters for as-deposited and as-annealed Cu-Ta films evidenced by XRD again indicate that solute tantalum atoms are in the solid solution with copper. After annealing, precipitations of tantalum-rich nanocrystalline phase appear in Cu-Ta films at and above 400°C. Thermal analysis results show exothermic transitions for high tantalum content films (Cu-14.9Ta films). Microstructures of both as-deposited and as-annealed Cu-Ta pseudoalloy films are examed by SEM and TEM. Ultra-microhardness results show an increase in hardness with tantalum contents for both as-deposited and as-annealed Cu-Ta films. Electrical resistivity measurements reveal that resistivities of as-deposited Cu-Ta films of low Ta contents (<1.7%Ta) decrease while a different trend is observed in high Ta content films, suggesting the improvement in the microstructure.

In this study thermomechanical processings were applied to three Zn-Al alloys, namely the micro-duplex Zn-22 wt.% Al alloy, pseudo-single α phase Zn-95 wt.% Al and pseudo-single β phase Zn-1wt.% Al for the strain softening and anneal hardening studies. The microstructure, hardness and compression S-S curves of these Zn-Al alloys were studied by using differential scanning calorimetry (DSC), scanning electron microscopy (SEM), microhardness measurements and compression tester. The results showed the occurrence of a strain softening phenomenon in Zn-Al alloys containing a substantial amount of β phase in the temperature range from -10℃ to 250℃ and an anneal hardening behavior in the strain softened Zn-Al alloys upon high temperature annealing. The mechanism of the strain softening behavior was found to be a DRX-induced softening during hot working, which can be facilitated by the formation of ultra-fine β grains with high-angle-boundaries; the mechanism of the anneal hardening behavior, on the other hand, was found to be the annihilation of the ultra-fine β grains by a high temperature grain coarsening treatment to retard the occurrence of the DRX-induced softening and to restore the “normal strength” of the alloy. A composite stress-strain curve model was proposed in this study to resolve the strain softening and anneal hardening behaviors in the dual-phase Zn-22 wt.％ Al alloy. By using this model detailed informations regarding to the deformation, the DRX (i.e. the strain softening) and the grain coarsening (i.e. the anneal hardening) behaviors in the β phase can be disclosed.

Abstract:
Orthodontic fixed appliances are used to correct dental malocclusions by optimizing tooth movement and associated bone remodelling. Currently, orthodontic archwires made of shape memory alloys (SMAs) are widely used to initiate these treatments. We conduct experiments on SMA wires in pseudo in-vivo conditions, complementary to ISO standards, to assess the influence of temperature and humidity and to highlight their expected mechanical behaviour for clinical use. For this, an in-house built measurement device was developed to carry out experiments at controlled temperatures (21°C and 35°C) and in dry or wet conditions (artificial saliva). The dental arch was reproduced by 3D printing. The results show that the temperature has a major influence on the delivered forces whereas wet or dry conditions seem to have less impact. Also, we emphasize that at 35°C (in mouth conditions), in wet or dry conditions, SMAs superelasticity is only effective for displacements up to about 3 mm when an entire dental arch is considered.

Abstract:
Shape setting is a fundamental step in the production route of Nitinol Shape Memory Alloys (SMAs) for the fixing of the functional properties, such as the shape memory effect and the pseudo-elasticity. The conventional method for making the shape setting needs the use of furnaces. In this work laser technology was adopted for performing the straight shape setting on commercially available Nitinol thin wires. The laser beam was moved along the wire length for inducing the functional performances. Calorimetric and pseudo-elastic response of the wires, laser annealed, were studied; high energy X-Rays diffraction was done for studying the evolution of the microstructure texture. It can be stated that the laser technology can realize the shape setting of thin SMA wires with pseudo-elastic properties; the wire performances can be modulated in function of the laser power.

Abstract:
A modified single lap shear test configuration, based on the Iosipescu geometry, is proposed for determination of the constitutive properties of solder alloys. An auxiliary device (extension unit) is introduced to improve the accuracy of measurement. The extension unit is attached directly to the specimen and it converts shear displacements to axial displacements, which are subsequently captured by a high-resolution extensometer. With aid of the extension unit, shear deformations are measured without compensating machine and grip compliance. The specimen configuration includes geometrical constraints at the solder/substrate interfaces in most electronic assemblies. Consequently, the results represent pseudo-continuum properties that take account for grain constraints at the solder/pad interface. They are properties that are more realistic for continuum mechanics based stress studies such as an FEM analysis.

Abstract:
Dendritic growth is best understood for pure substances growing into a uniformly supercooled environment. Under certain assumptions the standard growth theory can be applied to the directional growth of dendrites in a binary alloy. To apply the theory to technical multicomponent alloys so called ‘binary equivalent’ or ‘pseudo-binary’ models have been proposed. The basic question of ‘Is there a difference between dendrites of a binary or ternary alloy?’ has only partially been answered. A phase-field model applied to a ternary Fe-C alloy with a third fictive component will be used in this paper to compare ternary and binary equivalent phase-field simulations focussing on different component diffusivities. Results for directional dendritic solidification indicate negligible and relevant differences with respect to micro-segregation and micro-structure.

Abstract:
Shape memory alloys (SMA) have been an extensively used material for actuators in micro-electromechanical systems (MEMS) because actuation force and displacement are greatest in SMA amongst many actuator materials [1]. Of the alloys currently available for SMA actuators, the most popular system is Nitinol (or NiTi) due to its good oxidation resistance, reversible martensitic transformation, broad range of transformation temperatures (from -100 - 100 °C), and specific power density [2]. Current commercially available SMA wire has easily achieved no-load strain of 5% with medium gage SMA wires demonstrating an axial force capacity of 2 Newtons or more. While the potential use of SMA materials in a thermal-electric motor has been documented beginning in the 1980's, there are a number of new allows and fatigue-resistant materials that may lead to more general designs with a wide range of motions and applications. Shape memory alloys are a special type of material that exhibit two unique properties, pseudo-elasticity and shape memory effect (SME). SMA undergoes SME because of martensitic or diffusionless transformation where each atom has a slight displacement, creating observable changes throughout the structure as the allow changes states. This alloy has the ability, once heated, to return to its parent austenite phase where it exists at higher symmetry. Upon cooling, the material returns to one of many lower symmetry martensitic phases. This thermal cycle is shown in Figure 1. [3,4]. It is even possible for many variants of martensite to be present in the same material. Pseudo-elasticity is a rubber-like flexibility that allows the SMA to be contorted for a variety of purposes. Once contorted, the application of heat will cause the alloy to undergo martensitic transformation. Upon completion of the cycle, the alloy will have returned to its original shape. The development of SMA-based electromechanical devices delivers traditional mechanical motion with non-traditional methods. Rather than electromagnetic components rotating about a central axis to produce power, the rotary SMA motor utilizes contracting elements, and mush as spark ignition rotary engine, it can be designed to produce angular motion. Motion is accomplished with sequenced electrical signals sent across each element mounted between an eccentric crank. Rotary motion is produced during the power portion of the cycle for specific SMA elements under the application of an electrical signal. Based on this concept, our team developed a demonstration model with four active elements. We have demonstrated rotary motion of the device for an extended period of time, and we believe that macro-scale models can reduce the concept substantially and perhaps to the MEMS level.

Abstract:
Active Aerodynamic Systems (AAS) are aerodynamic control surfaces that use the shape memory mechanism of Nitinol wires which have been embedded into an elastic medium. Nitinol is an alloy of Nickel and Titanium which possesses pseudo-elastic properties, causing it to shrink a considerable amount when it reaches an activation temperature. By achieving accurate control of the Nitinol and integrating it into an airplane wing, a method for inducing rolling rate can be developed which contains fewer moving parts. With a well-developed implementation of this technology, controlled flight would be made more accurate, more responsive, and have lower turbulence. The shape of the system is manipulated using a microprocessor based digital control system. The control circuit will utilize pulse width modulation to precisely control the temperature of the Nitinol wire in order to change the curvature of the control surface with more accuracy. AAS aims to revolutionize the use of shape memory alloys in the design of more organic aerodynamic applications.
