Shape memory in Ti-10V-2Fe-3Al

Slip Resistance of Ti-Based High-Temperature Shape Memory Alloys

“…It is now well accepted that high-temperature Ti-based alloys represent a formidable class of new shape memory alloys. The research on Ti-based shape memory alloys dates back to key works in the 1970s through the early 1980s [1][2][3][4][5]. These alloys can be used in biomedical applications [6,7] in addition to exhibiting high-temperature shape memory response [8][9][10][11].…”

Anisotropy and Temperature Dependence of Young’s Modulus in Textured TiNbAl Biomedical Shape Memory Alloy

“…9,10) These alloys exhibit the shape memory effect and superelasticity due to the thermoelastic -00 martensitic transformation. [11][12][13][14][15][16][17][18][19][20][21] -Ti alloys with -00 martensitic transformation are therefore regarded as candidate new biomedical shape memory alloys to replace Ti-Ni. We have systematically investigated shape memory and the superelasticity of Ti-Nb and Ti-Mo alloys with third elements belonging to the 13-and 14-groups in the periodic table.…”

Shape memory characteristics of a near β titanium alloy

“…When the bending strain is high (for example 4.9%), the stress may be enough to activate slip as suggested elsewhere [13], and the strain by slip deformation on the martensite or ␤ parent phase is unrecoverable and leads to a limited recovery ratio. Duerig [15] showed that the magnitude of the shape memory effect in the Ti-10V-2Fe-3Al alloy was dependant on the magnitude of initial strain. The maximum recovery strain was about 3% at an initial deformation of about 4%.…”

“…This microstructure changes from ␣ to ␣ above the critical alloy content [14]. Orthorhombic ␣ martensite can be formed by transformation of the metastable ␤ phase during quenching or stress-induced transformation of retained metastable ␤ phase [15]. The shape memory effect is associated with the reversion of ␣ to ␤ in ␤ type titanium alloys during heating.…”
