文摘

Strain localization is studied in Ti-6Al-4V via digital image correlation. Former β phase boundaries play a critical role in strain localization. Strain is accommodated along the major axis of favorably oriented α lathes. Slip transmits across microtextured regions based on neighboring orientations.
