Anisotropy of the Young's modulus and microstructure of a recrystallized beta 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, S-11, of the alloy were calculated from the measured Young's moduli and the volume fractions of the texture components.
