A quantitative study of thermal cycling along the build direction of Ti-6Al-4V produced by laser powder bed fusion

During laser-powder bed fusion (l-PBF) the printed material is subjected to multiple fast heating and cooling cycles when the laser interacts with neighboring tracks or layers above. The complex thermal history influences the final microstructure and the macroscopic properties of the printed part. I...
