摘要：

Fretting fatigue crack initiation behaviour was investigated for its dependence on the microstructure of a alpha/beta titanium alloy, which ranged from homogeneous duplex to the fully transformed heterogeneous lamellar texture by increasing the Widmanstatten colony size. When the microstructure changed from homogeneous duplex to the fully transformed heterogeneous lamellar texture, the resistance to fretting fatigue crack initiation decreased. And, this was just the opposite of short and long crack behaviour where the resistance to crack growth increases when the microstructure changes from homogeneous duplex to the fully transformed heterogeneous lamellar structure.
