In-situ tailoring mechanical properties of metastable Ti15Mo alloy produced by selective laser melting

In-situ regulation of the isothermal ω phase and mechanical properties of selective laser melted Ti15Mo is achieved. The evolution of isothermal ω phase due to the intrinsic heat treatment significantly affects the mechanical properties. The yield strength and elongation range from 576 to 1095 MPa and 13.4%–54.9%, respectively.
