Abstract

The Magnesium alloys play significant role in the weight lowering of the means of transport. The principal difference between forming the magnesium alloys and steel is temperature used by magnesium. Although some forming operations of magnesium alloys can be done at room temperature, elevated temperatures are used in most applications. Because of the hexagonal close-packed crystal structure, the cold forming of magnesium alloys is restricted to mild deformation and generous bend radius. The magnesium plate is due to its lack of slipping systems hardly cold formable when the slip realizes itself only in basal planes. However, the slip takes place in pyramidal planes from 225°C as well. Formed magnesium alloys can be used as either BIW parts or the dashboard carrier in the automotive industry. AZ31 alloy is commonly used for such purposes. When considering the use of magnesium plates in BIW structure, a material characteristic verification were needed, which the stress-strain tensile test in temperature camera and strengthening curves. Such results serve to further design of pressing tool construction.
