|Issue Date:||15-Jun-1996||Citation:||Gupta, M.,Lai, M.O.,Soo, C.Y. (1996-06-15). Effect of type of processing on the micro structural features and mechanical properties of Al-Cu/SiC metal matrix composites. Materials Science and Engineering A 210 (1-2) : 114-122. ScholarBank@NUS Repository.||Abstract:||In this study, an aluminum based metallic matrix (Al-2wt.% Cu) was reinforced with SiC particulates using a conventional casting technique and a new disintegrated melt deposition technique. Microstructural characterization studies conducted on the samples taken from disintegrated melt deposition technique 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 and ultimate tensile strength of samples taken from disintegrated melt deposition technique when compared with 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.||Source Title:||Materials Science and Engineering A||URI:||http://scholarbank.nus.edu.sg/handle/10635/58206||ISSN:||09215093|
