Abstract

This study was carried out to evaluate the effect of deformation twinning in Ti-15Mo alloys. The material was rolled to reduce the thickness by 88% and recrystallized at 900°C for 10 min. To observe deformation twinning, electron backscattering diffraction was applied, and the grain boundary characteristic distributions were analyzed. Application of rolling and recrystallization promoted development of texture with a {111}//ND component, which was a result of the lower phase stability. In particular, material subjected to tensile strain showed dense deformation twins with a component of {332} <113> that promoted the strength, r, and n values without a significant decrease in elongation. These phenomena are attributed to the enhanced strain-hardening exponent due to deformation twinning.
