Abstract: In the present study an aluminium-based metallic matrix (Al-2wt%Cu) was reinforced with SiC particulates using conventional casting and partial liquid phase casting (rheocasting) techniques. Microstructural characterization studies conducted on the rheocast samples revealed a more uniform distribution of SiC particulates and good interfacial integrity between SiC particulates and metallic matrix when compared to the conventionally cast composite samples. Results of ambient temperature mechanical tests demonstrate an increase in 0.2% YS, UTS and ductility in case of rheocast samples when compared to the unreinforced and conventionally cast composite samples. The results of microstructural characterization and mechanical testing were finally rationalized in terms of the nature of processing technique employed to reinforce Al-2wt%Cu metallic matrix with SiC particulates. © 1995.
