Abstract

Magnesium matrix composites reinforced with SiCp particles were fabricated using the semi-solid stir casting process. The purpose of the study was to the effects concentration wt% SiCp and TiB of the mechanical properties of composites Al-Mg-2TiB/SiCp and Al-Mg-4TiB/SiCp. Variations (3, 6, 9 wt.%) SiCp/Al-Mg composites with different SiCp and TiB contents were successfully fabricated by semi-solid stir casting. Mechanical stirring technique carried out in conditions of semi-solid to obtain SiCp particles evenly dispersed. Effects of SiCp and TiB content on mechanical properties were studied by density, porosity, hardness test, impact test and microstructure images. The results indicate that SiCp particles disperse homogeneously in AZ81A matrix, and interfacial reaction between matrix and SiCp particles is effectively controlled. Distribution of SiCp reinforcement and interfacial bonding are improved by adding TiB. Additionally, the mechanical properties of composites are remarkably improved with the SiCp and TiB content increasing. The addition of (2 and 4 wt%) TiB gives grain refinement on the AZ81A matrix.
