Squeeze casting is known to overcome the defects that incur during the conventional casting processes. The near-net shape manufacturing ability and potential to yield higher hardness are the capability of the squeeze casting provided technical parameters are accurately controlled. In this research, optimization technique for squeeze casting process parameter is established by Taguchi technique to explore the correlation among the hardness and tensile strength. Four different process parameters namely squeeze pressure, melt temperature, die temperature and holding time were selected to perform the experiments using L16 orthogonal array. The composites obtained for optimum cast conditions were squeeze pressure 100 MPa, holding time 30 s, melt temperature 750 °C and die temperature 100 °C exhibited better hardness and tensile strength. The identified process parameters provide a favorable condition for processing the alloys directly on the melt up to the time of complete solidification. The results indicate that there exists a strong correlation between hardness and tensile strength. © 2018 IOP Publishing Ltd.
