On the role of cooling rate and temperature in forming twinned α’ martensite in Ti–6Al–4V
Sheng Cao,Sheng Cao,Bohua Zhang,Yi Yang,Qingbo Jia,Lei Li,Shewei Xin,Xinhua Wu,Qiaodan Hu,Chao Voon Samuel Lim +9 more
TL;DR: In this article, the mechanism of twinned martensite formation for selective laser melted Ti-6Al-4V was investigated by considering the alternating thermal stress and fast cooling from decreasing peak temperatures in selective laser melting thermal cycles.

Effects of the morphology of grain boundary α-phase on the anisotropic deformation behaviors of additive manufactured Ti–6Al–4V
TL;DR: In this article , the deformation-induced dislocations were found severely accumulated within the continuous grain boundary α-phase with the transverse loading direction, which corresponds to the strain localization, while uniformly distributed between the continuous GB-α and surrounding grains with the perpendicular tensile loading.
