Abstract
It is well known that the mechanical properties of Ti-6.5Al-3.5Mo-1.5Zr-0.3Si are closely related to its microstructure and texture. In this work, a novel treatment of electroshocking treatment (EST) was adopted to optimize the microstructure and improve the mechanical properties of this titanium alloy. The grain orientation, texture, and mechanical properties of Ti-6.5Al-3.5Mo-1.5Zr-0.3Si alloy under EST were characterized and analyzed. With the increase of EST time to 0.04 s, the resultant acicular secondary αs shows a tendency of spheroidization and the increase in grain diameter, which leads to a little decrease in hardness and yield strength. The increase in EST time to 0.06 s resulted in the precipitation of martensitic phases with high aspect ratios and a reduction in grain size in Ti-6.5Al-3.5Mo-1.5Zr-0.3Si alloy, as well as generating a more uniform texture distribution. The optimization of microstructure and texture significantly enhances the hardness and yield strength. The results in this work demonstrate that EST can serve as a novel method to regulate the microstructure and mechanical properties of Ti-6.5Al-3.5Mo-1.5Zr-0.3Si alloy.
