摘要

Abstract

BSTRACTTo improve the mechanical properties of additively manufactured parts

specific heat treatments must be developed. Annealing of electron beam-melted Ti–6Al–4V was performed at sub-transus temperatures and followed by water quenching. Such treatments generate an

′ dual-phase microstructure. Microstructural and mechanical characterizations revealed that the heat-treated specimens show a broad range of tensile properties

depending on the fraction of martensite. The specimens treated between 850°C and 920°C exhibit an increase in strength and ductility

which is related to a remarkable hardening behavior. Work-hardening is attributed to kinematic hardening arising from the mechanical contrast between the

and

′ phases.
