doi:10.13251/j.issn.0254-6051.2021.09.026

Abstract

Abstract: Effects of different heat treatment process on microstructure and room temperature mechanical properties of the Ti80 titanium alloy bars were studied. The results show that with the increase of heat treatment temperature, the microstructure of the Ti80 titanium alloy changes from equiaxed structure to widmanstatite structure. When plastic forming is required in the later period, it is appropriate to choose the heat treatment process of air-cooling after heating at 850 ℃ for 80 min. After the heat treatment process of heating at 750 ℃ for 80 min and then air-cooling, the strength and plasticity of the Ti80 titanium alloy bars match well.

Key words: Ti80 titanium alloy, heat treatment, microstructure, mechanical properties
