| Summary: | Particulate reinforced aluminum matrix composites are increasingly being used in commercial applications, owing to their superior physical and mechanical properties, compared to the conventional alloys. This study aims to investigate the compaction conditions of 2124 Al SiC
p
composites to determine the optimum parameters. Through powder metallurgical techniques 2124 Al composites were produced. The pressure required for compaction was optimized and a pressure–density relation was established. Optimum compaction pressure has been identified as ~180 MPa (for 2124 Al alloy), ~190 MPa (for 2124 Al/10 % SiC
p
), ~200 MPa (for 2124 Al/15 % SiC
p
) and ~210 MPa (for 2124 Al/20 % SiC
p
). Also compaction pressure versus density relationship was established for composite powder based on Heckel’s expression. Also different compaction stages were identified. This inference could be used as guideline for the selection of correct capacity compacting machines and in the design of the compaction tooling so as to obtain desired level of green strength. |
