Abstract
Aluminium metal matrix composite is developed using powder metallurgy, with number of different operational factors considered. The three most important operational factors are sintering time, sintering temperature, and compaction pressure. Investigations are conducted using L9 orthogonal array as the experimental design. Density, Vickers hardness, and compressive strength are determined through experiments. The S/N ratio based on Taguchi's law and a number of anomalies accomplished were used to determine the effect of individual input parameters (ANOVA). The main effect plots identified the optimal parameter settings for obtaining a less density, a higher hardness, and a higher compressive strength. In addition, the ANOVA analysis confirmed that the best metal matrix composite material is produced at the optimal sintering time and average temperature and compaction pressure for generally classified levels.
