Abstract

© 2016. Electron beam melting (EBM) has been used to manufacture β-type Ti-24Nb-4Zr-8Sn porous components with 70% porosity. EBM-produced components have favorable structural features (i.e. smooth strut surfaces, fewer defects) and an (α + β)-type microstructure, similar to that subjected to aging treatment. EBM-produced components exhibit more than twice the strength-to-modulus ratio of porous Ti-6Al-4V components having the same porosity. The processing-microstructure-property relationship and deformation behavior of EBM-produced components are discussed in detail. Such porous titanium components composed of non-toxic elements and having high strength-to-modulus ratio are highly attractive for biomedical applications.
