Notes:
The characteristics of microstructures in friction stir (FS) weld of 304 austenitic stainlesssteel were examined. The stir zone (SZ) and thermomechanically affected zone (TMAZ) showeddynamically recrystallized and recovered microstructures, respectively. The hardness of the SZ washigher than that of the base material and the maximum hardness was located in the TMAZ. Thehigher hardness in TMAZ was attributed to high density of dislocations and sub-boundaries.Electron microscopic observations revealed that ferrite and sigma phases were formed in austenitematrix in the SZ during friction stir welding (FSW)
