Lately, a growing volume of research has been conducted on studying the effects of equal channel angular extrusion processing. Equal channel angular extrusion (ECAE) or equal channel angular pressing (ECAP) is a severe plastic deformation (SPD) technique, which presses the test materials through a die with two channels which are equal in cross section and intersecting at a certain angle. After the deformation, the test materials will still retain its original cross-section being able to repeat the process to many cycles. This method improves the mechanical properties of the processed materials because of the ultrafine grained structures resulted. Present paper intends to make a qualitative investigation of the Mg-Zn-Zr samples processed through ECAE.
