Abstract

The effect of three type of heat treatments on the microstructure and tensile properties of a novel metastable β-titanium alloy Ti-6Mo-5V-3Al-2Fe-2Zr was investigated, namely solution and single-stage aging, solution and two-stage aging, as well as solution and furnace cooling. The results show that: compared with the solution and single-stage aging treatment, the strength of the alloy was improved with the decrease of the spacing of secondary α phase precipitated within grains and the increase of its volume fraction by solution and two-stage aging treatment. Continuous α phase formed at grain boundary resulted by the above two heat treatment processes, which leading to poor plasticity of the alloy. Compared with the above two heat treatment processes, the heat treatment of solid solution and furnace cooling could induce obviously the decrease of the spacing of the intracrystalline secondary α phase precipitated, thus increase the amount of α_wgb phase formed along the grain boundary and grew into the grain, thereby increase significantly the strength and plasticity of the alloy i.e., the tensile strength of the alloy reaches 1421 MPa, and the fracture elongation is 7.7%. Relative to the volume fraction of the secondary α phase, the spacing is the main factor affecting the strength of the alloy. With the decrease of the spacing of the secondary α phase, the alloy strength increases.

Key words: metallic materials metastable β titanium alloy furnace cooling secondary α phase tensile property
