Abstract

In this study, the annealing AZ61 magnesium alloy (AO) was studied on friction stir process (AF). The AF specimen revealed that the non-uniform microstructure consists of fine and coarse grains in the stir zone. The FSPed specimens have shown improvement on microstructure and the particles are of matrix distributed over friction stir zone by stabilization heat treatment (AH). The specimens acquired a unique texture twins and basal slip system. The AF and AH specimens possess lower yield stress via friction stir processes and the uniform microstructure of the AH specimen increases the tensile ductility at tensile temperature of 100℃. On the other hand, the AH specimen has the amount of second phase particles and possesses great smooth surface on punch-shear test at 100℃.
