Embodiment 1
[0014] The rod-shaped hot-rolled Ti6Al4V alloy was placed in a high-temperature muffle furnace at 1000 °C for 45 min, and then water-cooled; then the alloy was kept at 480 °C for 3 h, and then air-cooled. The purpose is to heat continuously rolled Ti6Al4V alloy at 1000°C for 45 minutes in a high-temperature muffle furnace, and perform solid solution treatment on the alloy to transform the α phase into β phase in the alloy; , Aging treatment is carried out on the alloy, and the needle-like α phase is precipitated at low temperature, so that the microstructure of the alloy is transformed into a basket structure, and the durable life of the alloy is improved.
