Analysis of the Grain Orientation and Tezture of Friction Stir Welded Magnesium Alloy
(0) The grain orientations and microtextures in a friction-stir-welded magnesium alloy AZ80A were analyzed by Orientation Imaging Microscopy (OIM). The results showed that times random of grain orientations in the nugget zone were not strong and orientations were variety. They brought on very fine equiaxed grains. It also showed that deformation texture of 1,-1,0,4<1,0,-1,0>was a few departure 20deg from the sample normal, The grains in the nugget zone from the base metal inherited the deformation texture of 1, -1,0,4<1,0,-1,0>. It was concluded that re-crystallized grains in the nugget zone formed by a continuous dynamic re-crystallized mechanism.
