In this work the effect of temperature on grain refinement of Mg-3Al-1Zn alloy (AZ31B) processed by equal channel angular pressing using route A is described. The deformation sequences consisted of equal channel angular pressing passes at 200C followed by passes at 150°C. Nonhomogeneous grain size distribution promotes shear band formation at 150°C. Shear bands with microcracks inside were analyzed by electron backscatter diffraction technique.
