چکیده انگلیسی
The sequence of activation of deformation mechanisms in a near-β Ti-5Al-5Mo-5V-3Cr alloy quenched from the β-field is investigated as a function of strain during uniaxial compression at 0.001â¯sâ1 up to ε = 0.041. Bulk in situ high energy synchrotron X-ray diffraction is applied to follow continuously the evolution of the microstructure of the alloy during deformation and is complemented with metallographic analysis. Stress induced β â αⳠtransformation takes place together with grain rotation of β upon reaching the yield stress of the alloy at ε = 0.021. During further loading, formation of β sub-grain cells is activated at ε ⥠0.03. The stress-induced martensite forms with a strong texture of {200} αⳠplanes perpendicular to the compression direction.
