Abstract
This study focuses on the manufacturing process of a magnesium alloy impeller used for the fuel cell car using the hot forging technology. The impeller has the very complicated shape with sharply curved blade and thus generally produced by mechanical machining or casting process. However, since these technologies give the high manufacturing cost or poor mechanical properties, the forging technology is required to make the high-quality impeller with the lower manufacturing cost. In order for production of the impeller by forging technology, the parametric studies using finite element analyses were carried out to find the optimal perform shape of impeller made of magnesium alloy AZ 31 and finally die design was proposed based on the simulation results.
