Abstract Scope |
Additive Manufacture is currently being used for the production of metallic components because it can offer reductions in cost and waste. AM Ti64 has received attention because of the high material cost and the innate ability of AM to minimize material waste. Originally, the Ti64 alloy was developed for casting applications which have very slow cooling rates. Its property combinations are still desired for AM built parts, but the much higher cooling rates, as high as 106K/s, associated with AM result in a distinct and metastable microstructure and, subsequently, distinct material properties. Post-build heat treatments are usually used on Ti64 components produced by AM to drive the as-built microstructure closer a wrought equivalent in microstructure and properties. In this work, we have collected diffraction data during in-situ heat-treating of AM Ti64, made with various processes, in order to monitor the microstructural evolution of the material. |
