Abstract

Solution treatment (ST) can be considered as an effective method with multifunctional effects on the material properties. However, re-precipitation effect of ST on the selective laser melted (SLM) Ti-12Mo-6Zr-2Fe (TMZF) alloy have not been revealed. In this work, microstructural evolution and mechanical properties of SLM TMZF before and after a ST were studied. Triggered by the element diffusion-driven factor, as-fabricated (AF) samples with full β-Ti phase transformed into ST samples with α″-Ti phase and β-Ti phase during ST. Moreover, re-precipitation effect caused by α″-Ti phase significantly improved the mechanical properties of SLM TMZF.
