Abstract

This paper presents the first report on the development of weak-textured microstructures and resulting reduced in-plane anisotropy of mechanical properties in commercially pure titanium (CP-Ti) fabricated by electron beam melting (EBM). The as-built specimens exhibited fine grain structures with weakened crystallographic textures. The β → α' martensitic transformation after solidification was responsible for the weak textures as well as the relatively high strength. The results suggest that it is possible to use EBM to produce isotropic CP-Ti components, which cannot be obtained by conventional processes.
