Phase Transformation of Anisotropic Shape Memory Alloys: Theory and Validation in Superelasticity [PDF]
, 2015 In the present study, a new transformation criterion that includes the effect of tension–compression asymmetry and texture-induced anisotropy is proposed and combined with a thermodynamical model to describe the thermomechanical behavior of ...

Annual Review of Materials Science, 1988 In some alloys, a given plastic strain recovers completely when the con cerned alloy is heated above a certain temperature. This phenomenon, shape memory effect (SME), was observed in Au-Cd (1) and In-Tl (2) alloys in the first half of 1950s. However, SME was not a focus of research until it was found in a Ti-Ni alloy (3) in 1963, when the phenomenon ...

Brief Overview on Nitinol as Biomaterial
Advances in Materials Science and Engineering, 2016 Shape memory alloys remember their shape due to thermoelastic martensitic phase transformation. These alloys have advantages in terms of large recoverable strain and these alloys can exert continuous force during use.
