Deformation Properties of TiNi Shape Memory Alloy
In order to describe the deformation properties due to the martensitic transformation and the R-phase transformation of TiNi shape memory alloy, a thermomechanical constitutive equation considering the volume fractions of induced phases associated with both transformations is developed. The proposed constitutive equation expresses well the properties of the shape memory effect, pseudoelasticity...
متن کاملThermomechanical Properties of TiNi Shape Memory Alloy
The thermomechanical properties of shape memory effect and superelasticity due to the martensitic transformation and the R-phase transformation of TiNi shape memory alloy were investigated experimentally. The transformation line, recovery stress and fatigue property due to both transformations were discussed for cyclic deformation. The thermomechanical properties due to the R-phase transformati...
متن کاملLaser-Welding of a Ni-Rich TiNi Shape Memory Alloy : Mechanical Behavior
A Nd:YAG laser was used for joining a pseudoelastic Ti-51.5 at.% Ni shape memory alloy. Tensile tests on sheet metal of 0.5 mm thickness were performed at temperatures of -40°C, +20°C and 1 10°C, representing the martensitic, pseudoelastic and austenitic condition, respectively. Laser-welded specimens exhibited an ultimate tensile strength of about 820 MPa not affected by the test tempefature. ...
