The influence of temperature and strain rate on the deformation response and microstructural evolution during hot compression of a titanium alloy Ti-6Al-4V-0.1B

► Investigation on deformation behavior of Ti-6Al-4V-0.1B in (α + β) regime. ► Kinking of α/β lamellae at low temperatures. ► Early softening and equiaxed α grains at higher temperature. ► Accelerated globularization due to strain accumulation around TiB particles. ► Early globularization and removal of instability due to multiple slip.
