Abstract

Squeeze casting process is widely employed for the production of automotive and aerospace components. The research on squeeze casting is largely focused on light weight alloys nowadays. In particular, the research on squeeze casting is highly concentrated upon aluminium alloys and their composites in the recent years. In this attempt, aluminium alloy AA6061 was reinforced with silicon nitride (Si3N4) particles and the different grades of composites were developed by squeeze casting process. The parametric optimization was done by using Taguchi method. The parameters namely pressure, die temperature and weight percentage of Si3N4 particles were varied each at three levels. The mechanical properties exhibited by the squeeze cast composites were evaluated. It was observed that the component which was produced at the near optimal parameter setting (pressure of 100 MPa, die temperature of 275 oC and 6% of Si3N4) yielded higher values for mechanical properties of the components


Keywords: Squeeze casting, AA6061, Si3N4, Impact strength, Microhardness.
