Effect of Cooling Rate on Tensile Properties of Ti-5Al-5Mo-5V-3Cr Alloy

Article Preview

Abstract:

The effects of cooling rate on the tensile properties of Ti-5Al-5Mo-5V-3Cr alloy with different microstructures were investigated at room temperature. The results indicate that as the cooling rates (water quench, air cooling and furnace cooling) get slower, the quantity and size of primary α phase of Widmanstatten microstructure and bi-modal microstructure increase, resulting in lower strength but higher ductility. The alloy from solution treatment at 820°C for 1 h followed by air cooling and aging treatment at 580°C for 4h is in good balance of strength and ductility.
