摘要

Ti-6Al-4V alloys are utilized in various industrial applications. Here, the effect of heat treatment on the microstructural evolution and mechanical properties of the Ti-6Al-4V alloys, which were fabricated by selective laser melting (SLM), was investigated. The as-fabricated-1133 K sample possessed a significantly higher ductility than that of the as-fabricated sample. This was attributed to the precipitation of the micro/nanoscale β and athermal ω phases that was accompanied by the equiaxial transformation of the β columnar grains.
