Effect of Preforming on Drawing of AZ31 Alloy Thin Plate

Magnesium alloy is one of the light metallic materials which is utilized in industry, but it is difficult to do its plastic working in the ordinary temperature. After preforming to AZ31 magnesium alloy thin plate, the material has a performance of high drawing greatly. In this study, preforming is rolling processing. The preforming material has more high drawing as ratio of reduction in thickness increases, e.g. high preforming material (reduction in thickness : 34%×2) is able to be formed under temperature at 100°C.
