The interactions among thermal history, plastic deformation and residual stresses in the friction stir welding (FSW) process under different welding parameters have been widely considered a crucial issue and still not fully understood. In the present... Read More about Heat generation, plastic deformation and residual stresses in friction stir welding of aluminium alloy.

Coupled quantitative modeling of microstructural evolution and plastic flow during continuous dynamic recrystallization (2022)
Journal Article
