Structural componests for aerospace, electronics and automobile industry are the main applications for magneium alloys due to their lightweight and high specific strength. The adoption of magnesium alloys in sheet forming processes is still limited, due to their low formability at room temperature caused by the hexagonal crystal structure. This study aims to confirm improvement and characteristics of formability of a magnesium alloy sheet by using local heating and cooling technique. The deformation behaviour and temperature distribution in cylindrical deep drawing of magnesium alloy(AZ31) at various temperature for the blank and tool(holder and die)and at a punch speed of 10㎜/min, 100㎜/min while the punch was kept at room temperature by cooling water are simulated by F.E.M. and done by experiments.
