Abstract

The effect of processing parameters on the microstructure was investigated on three α+β alloys, namely Ti6Al4V (Ti64), Ti6Al2Sn4Zr6Mo (Ti6246) and Ti6.5Al3.5Mo1.5Zr0.3Si (TC11) fabricated by laser powder bed fusion (LPBF). Electron Backscattered Diffraction (EBSD) was used to identify microstructural characteristics, including prior beta grains (PBGs) structure, hierarchical lath morphology and orientation. Acicular martensitic (α’) laths form within the PBGs following a crystallographic relationship. The martensite displays a hierarchical structure.
