Heat treatments tailored for additive manufactured Ti-6Al-4V can be used to attain desirable microstructures associated with superior mechanical properties. Rapid heat treatments, for example, can be used to recrystallise the microstructure of laser powder bed fusion (L-PBF) Ti-6Al-4V to obtain refi...
