Achieving 100 %-efficiency joint in rotary friction welding of thin-walled Al alloy drive shafts via high friction pressure and short-time post-weld heat treatment

Achieving 100 %-efficiency joint in rotary friction welding of thin-walled Al alloy drive shafts via high friction pressure and short-time post-weld heat treatment

Rotary friction welding (RFW) was employed to join large diameter thin-walled Al–Mg–Si–Cu alloy drive shafts. The coupling effects of friction pressure and post-weld heat treatment (PWHT) on the microstructure evolution and mechanical properties of the RFWed joints were investigated. Increasing the...
