The effect of heat treatment on microstructure, microhardness, and pitting corrosion of Ti6Al4V produced by electron beam melting additive manufacturing process

There has been limited studies on corrosion behaviour of post-processed electron beam melted (EBM) Ti6Al4V, given that the factors affecting resistance AM Ti6Al4V remain unclear. This paper proposes using heat treatment method to improve pitting EBM Ti6Al4V. Different profiles alter microstructure A clear trend is observed between microhardness and α lath width. As-printed exhibits an inferior potential, while provided a significant improvement in resistance. study finds β phase fraction better indicator than width for Solution air-cooled ageing heat-treated good mechanical properties, even performs commercial cast
