WELDING OF NITINOL BY SELECTED TECHNOLOGIES
Acta Polytechnica, 2019 Nitinol is a perspective alloy that is difficult to weld because of its high sensitivity to heat, atmospheric gases and the NiTi phase instability. We evaluated several welding techniques with regard to their applicability to weld fine pseudoelastic NiTi

Impact response of pseudoelastic nitinol
Journal of Applied PhysicsThe response of polycrystalline nitinol with solely austenite structure was studied in three series of planar impact tests characterized by loading of the nitinol samples of 0.5–10 mm thickness by 1 mm thick aluminum impactor accelerated up to velocities of about 387, 429, and 567 m/s.

Entropy, 2018 This study focuses preliminarily on the intra-tertiary catchment (TC) assessment of cross MAR pseudo-elasticity of entropy, which determines the impact of changes in MAR for a quaternary catchment (QC) on the entropy of another (other) QC(s).

Bending of pseudoelastic NiTi tubes
International Journal of Solids and Structures, 2017 Abstract Tension induced phase transformation in pseudoelastic NiTi leads to inhomogeneous deformation with the austenitic and martensitic phases coexisting. Deformation of nearly 7% is recovered on unloading during which the deformation is again inhomogeneous.

THERMOMECHANICAL COUPLINGS AND PSEUDOELASTICITY OF SHAPE MEMORY ALLOYS
International Journal of Engineering Science, 1998 Energy balances of a polycrystalline CuZnAl Shape Memory Alloy are performed using infrared and calorimetric techniques. The experiments underline the main role of temperature variations induced by deformation process on the stress–strain curves. A thermodynamic analysis shows variations essentially due to the latent heat of phase change and indicates ...

R-Phase Transformation Evolution in NiTi SMA Wires Studied via the Internal Friction Technique
CrystalsThe specific damping capacity variation of heat-treated NiTi was observed during a pseudoelasticity test. The detailed B2 → R-phase transformation process in cold-drawn NiTi wires undergoing middle-temperature aging was studied via X-ray diffraction ...
