Microstructure, tensile properties and corrosion behavior of friction stir processed Mg-9Li-1Zn alloy

The microstructure, tensile properties and corrosion behavior of friction stir processed Mg-9Li-1Zn alloy were investigated. The results show that the microstructure changes from the initial elongated grains of the α-Mg and β-Li phases to refined equiaxed grains after friction stir processing. Friction stir processing results in remarkable grain refinement and random distribution of crystallographic orientations. The mean grain size of the α-Mg...
