Investigation of microstructural match at friction welded TC17/TA19 interface based on β reconstruction under various frictional linear speeds

TC17 (α+β titanium alloy) and TA19 (near-α titanium alloy) are often joined in aerospace compressor rotors by rotary friction welding, but their differing phase transformation behaviors cause a mismatched microstructure at the weld interface. This study produced rotary friction welds at various line...
