Recently, magnesium alloys have drawn much attention as an appropriate material for mobile appliances which usually be lighter in weight. As well known, plastic working of magnesium alloys are quite difficult stemmed from their HCP structure. We have successfully developed a new boss forming process on thin plate of light alloys in circumferential environment. In this study, microstructures and some mechanical properties of the bosses shaped from AZ31Mg alloy plate are examined and discussed. We have found that impact strength of the bosses is about the same as or larger than that of the base alloy.
