ABSTRACT

Aluminum metal matrix composites are finding increased applications in many areas. Adding of the third element to the metal matrix make the composite hybrid. In this work Aluminum 7068 as matrix and Silicon Carbide and Alumina as reinforcement has been used. The %wt of reinforcement are varied to study the difference in aluminum property. Following are the samples are first sample is Al7068 with 2% SiC and 8% Al₂O₃, second sample consist of Al7068 with 4% SiC and 6% Al₂O₃ , third sample consist of Al7068 with 6% SiC and 4% Al₂O₃, and the fourth sample is of Al7068 with 8%SiC and 2% Al₂O₃. The materials are obtained by stir casting technique. The casted composite specimens were machined as per ASTM standards. The aim is to study the mechanical and tribological properties of Al-7068 alloy reinforced with SiC and Al₂O₃  composite with various weight fraction were prepared by stir casting method.

Keywords: Al-7068 alloy, SiC, Al₂O₃, Stir Casting, Mechanical and Tribological properties.
