Effect of Heat Treatment Condition on Texture in Ti-Mo-Al-Zr Shape Memory Alloy

Article Preview

Abstract:

Effect of solution-treatment condition on texture of a Ti-Mo-Al-Zr shape memory alloy was investigated by X-ray pole figure measurement. Ti-Mo-Al-Zr alloy is a Ni-free and β-Ti based biomedical shape memory alloy. Unlike Ti-Nb system alloys, {110}β <001>β recrystallization texture was developed by the solution-treatment above β-transus as the reduction rate increases. However, this texture disappeared by the solution-treatment below β-transus and {531}β <134>β recrystallization texture was strongly developed. It was found that precipitation of hcp α phase has a significant effect on recrystallization texture in this alloy.
