Microstructure and texture evolution during β extrusion of boron modified Ti-6Al-4V alloy

► Equiaxed β grains for two alloys due to dynamic recrystallization. ► Large shear bands parallel to the extrusion direction only for Ti-6Al-4V. ► Phase transformation without TiB particles for Ti-6Al-4V-0.1B. ► Limited variant selection and stronger texture for Ti-6Al-4V. ► Minor anisotropy in hardness after extrusion for two alloys.
