Magnesium alloys have the lowest densities among metals in practical use, and have properties such high specific strength, effective electromagnetic interference shielding and high vibration damping ratio. Thus, there are many applications of these materials in automotive and electric parts. However, they have little use as metal-forming products, because of their poor plastic deformability at normal temperatures, and because they are expensive to produce. To promote products manufactured by metal forming, rolling technology is necessary to produce thin sheets that have suitable mechanical properties and surface qualities. For this purpose, the equivalent stress and strain relations are investigated by means of a plane strain compressing test for hot-rolled Mg-alloy AZ31 sheets. These materials are experimentally rolled with or without lubrication under temperatures ranging from 293K to 523K. The rolling force, plastic deformability and surface quality are investigated. Grain structures and their uniformity are also observed. Finally, the effect of friction between the rolls and the deforming material on the uniformity of the grain structure is discussed in this work.
