Three processing routes of equal channel angular extrusion (ECAE) were used to process Mg alloy. Tensile strengths, grain sizes and textures of these processed billets were measured to investigate the effect of processing route on the mechanical properties, and the strengthening mechanism. Route A is the only route that can increase the strength by ECAE. A multiple-temperature ECAE procedure has been developed to produce high-strength Mg alloy, which is a combined result of submicron grain structure and texture strengthening.
