ABSTRACT With the development of new near-net shape forming process, powder metallurgy has been widely used in the manufacturing of automobiles and their parts. This paper proposes a novel integrated product and process development (IPPD) methodology for clutch hub via powder metallurgy, and the manufacturing-oriented design is carried out. The three-dimensional model of the hub is established and simulated by ANSYS. A Fe–C-Cu–Ni–Mo material system for the powder metallurgy clutch hub is created, and a corresponding process scheme is developed. Through material metallographic analysis and experimental verification, the results show that the powder metallurgy clutch hub developed by the IPPD technology can meet the requirements of automotive applications in terms of strength and durability. The IPPD methodology and new near-net shape forming technology can be widely applied to automotive parts such as gear flanges.
