Notes:
Residual strain profiles in friction-stir processed (FSP) AZ31B magnesium-alloy plates weremeasured using neutron diffraction. Two different specimens were prepared to investigate theinfluences of the tool shoulder and the tool pin on the residual-strain profiles: (Case 1) a plateprocessed with both the stirring pin and tool shoulder, i.e., a regular FSP plate subjected to both theplastic deformation and frictional heating, and (Case 2) a plate processed only with the toolshoulder, i.e., subjected mainly to the frictional heating. The results show that the strain profiles ofboth cases are qualitatively quite similar. The longitudinal strain is mainly tensile with itsmaximum near the bead of the FSP plate. On the other hand, the transverse and normal strains aremildly compressive in both Cases 1 and 2
