Improving joint performance of friction stir welded 2195-O Al–Li alloy by post-weld heat treatment and rolling deformation

Post-weld heat treatment and rolling deformation are used to improve the mechanical properties of 2195-O Al–Li alloy friction stir welding (FSW) joints, and the effects on the grain structure, precipitation behaviors, hardness distribution, and tensile performance are discussed. Microstructural char...
