Abstract:The effects of different forging processes and heat treatments on microstructures and properties of TC11 titanium alloy were investigated by means of optical microscope observation, mechanical property test, fatigue property test and scanning electric microscope fractography analysis. The results show that the high temperature homogenizing forging is suitable for TC11 titanium alloy. After high temperature homogenizing forging, the as-forged microstructure can lay a good basis to the next heat treatment, which is beneficial to improving comprehensive properties of TC11 titanium alloy.
Key words: TC11 alloy forging; high temperature homogenizing treatment; tri-modal microstructure; mechanical property; strength-toughness match
