Abstract
Abstract
In this study, an LM13 metal-matrix composite was fabricated using two reinforcement particles (hard and soft) of titanium diboride and zirconium carbide. An experimental design was used to narrow down the trials. The significance of the model was tested using Student’s t-test and p values. The response surface statistical method was used to obtain the optimum process parameters for the high-strength hybrid metal matrix composite. From the experimental results, a maximum strength of 209 MPa was gained at a stirrer speed of 700 rpm, weight fraction of TiB2 and ZrC of 9 %, and casting temperature of 675 °C. The ANOVA results showed that TiB2 was the main influential process parameter, followed by the stirrer speed, casting temperature, and zirconium boride. The microstructure showed a fine and uniform distribution of reinforcement particles in the LM13 matrix. The fracture surface exhibited a mixed fracture pattern, which was due to the good bonding between the reinforcement and matrix at the interface.
