Abstract
The object of the present work is to research the microstructure evolution of AISI 304 stainless steel (304SS) joined by rotary friction welding. The dynamic recrystallization (DRX) and texture formation process were analyzed by optical microscope and electron back-scattered diffraction (EBSD) technology. The results showed that DRX, which emerges on the torque rising stage, mainly occurs in the welding zone, and completes on the torque quasi-steady stage. Furthermore, obvious shear type texture ({110} <112>) forms in the joint of 304SS.
