Influence of thermo-mechanical parameters on texture and tensile behavior of friction stir processed Mg alloy

The influence of strain rate and temperature during friction stir processing (FSP) on the texture and tensile behavior of a Mg alloy has been investigated. By varying key processing parameters systematically, i.e. rotation and travel rates of the tool, a series of FSP specimens were prepared with a wide range of thermo-mechanical inputs in terms of the Zener–Hollomon parameter (Z). Neutron diffraction results showed a dramatic change in texture as Z increased. The resulting tensile behavior in the stir zone also illustrates the influence of Z.
