In addition to the great merits of producing three-dimensional complex components from metallic powders in additive manufactured parts, the microstructural features can be tailored by the intrinsic heat treatment (IHT), i. e., cyclic re-heating without any additional post-treatment of the printed samples. Here we report that the microstructural configurations can be widely manipulated in an additive manufactured Ti-5Al-5Mo-5V-1Cr-1Fe (Ti-55511) near ? titanium alloy, with an emphasis on the effect of IHT on the in-situ precipitation of ? phase. The typical as-printed samples consist of prior-?...
