摘　　要：Magnesium alloys are best known for their light weight and high strength-to-weight ratio.In the forging process of magnesium alloys,hot working of has been often carried out.However,the strength of the material is reduced because the material temperature reaches the recrystallization temperature during hot working.Therefore,the cold method working is required to maintain or increase the strength of a material.In this study,we have designed experimental equipment to examine whether the forming of magnesium alloy is possible in the cold working by utilizing underwater shock wave,and the hardness of the material changes by receiving the underwater shock wave.Experimental results revealed increase in coefficient of extension and hardness of materials after receiving a shock wave.
