상용 고강도 마그네슘 합금을 이용한 컨트롤 암 개발

The forging of magnesium is restricted to a few industries that aerospace parts. As increasing interests in the environment and enforcing strong regulations on exhaust gases and carbon dioxide in developed countries, efforts into developments in magnesium forging techniques have been making more briskly with transportation machine maker as the center. In particular, growing demands for a fuel-efficient vehicle, various efforts into lightweight of parts are putting forth. In this work, high strength commercial AZ80 and ZK60 Magnesium Alloys were forged in order to observe the changes in characteristics to the process. Changing variable forging temperature and forging speed of magnesium feedstock, magnesium control arms for chassis component were manufactured. Carrying out different heat treatments (T4 and T6), the changes in characteristics were investigated.
