A Study on the characteristics of the cast using forged insert

까단조형 인서트를 이용한 주물재의 특성연구

In this study, the casting process using forged insert was applied to manufacturing a knuckle, in order to prove that application of casting process using forged insert is likely to get the effect of light weight and superior mechanical characteristic compared with existing casting products. Firstly, in the forging experiment, it was confirmed that the optimal configuration of the forged insert could be predicted by FE analysis. And by using FVM (Finite Volume Method) software, it was verified that a proposed casting design was available. To identify the mechanical characteristic of the final casting product, the microstructual observation and hardness test were performed at the boundary zone between forging and casting part.
