Abstract

Friction stir welding was conducted on a 430 austenitic stainless steel plate with thickness of 2 mm. The welding procedure was performed at a welding speed of 50 mm/min and rotational speed of 400 rpm. Microstructure observations showed high fraction of low angle grain boundaries formed in the thermo mechanically affected zone through the occurrence of dynamic recovery. Severe grain refinement took place in the stir zone with the formation of high fraction of high angle grain boundaries through dynamic recrystallization. Calculated pole figure showed that shear texture developed in the stir zone.
