Mg alloys have attracted great attentions in the automotive industry due to their lightweight characteritics. Their wider applications are still limited by the low formability at room temperature as well as low strength. Severe plastic deformation (SPD) processes have been suggested to resolve these problems for a decade. Nevertheless, the limited size of SPD-processed Mg alloy can be another problem for mass production. This work proposes the multi-pass caliber-rolling (MPCR) as an alternative way to obtain high-strength bulk Mg rods applicable in the industry. It has been confirmed in steels and Ti alloys that this process can manufacture ultrafine-grained bulk rods. The authors expands the MPCR process to the field of Mg alloys, and investigates their microstructural evolution and mechanical enhancement.
