Abstract

Anisotropy of the Young's modulus and microstructure of a recrystallized β Ti-Mo-Al-Zr alloy with a Goss texture were investigated. Specimens were solution-treated at 1173 K for 3.6 ks after cold rolling with a reduction rate of 99%. The {011}<100> Goss recrystallization texture developed as a major texture component. The Young's modulus was evaluated by tensile tests using a strain gage method. Anisotropy of the Young's modulus depending on the loading direction was observed: The lowest and highest values of the Young's modulus were 44 and 77 GPa, respectively. The compliance anisotropy factor, J, and the characteristic modulus, S11, of the alloy were calculated from the measured Young's moduli and the volume fractions of the texture components.
