Heat-treatment effects on mechanical properties and microstructure evolution of Ti-6Al-4V alloy fabricated by laser powder bed fusion

Recently, the Ti-6Al-4V alloy fabricated by laser powder bed fusion has been widely studies. According to the high cooling rate, the strength of 3D printed Ti-6Al-4V alloy usually higher than that made by traditional process. In the meanwhile, the residual stress or microstructure feature that cause...
