Investigations on tensile fractography and wear characteristics of Al7075-Al2O3-SiC Hybrid Metal Matrix Composites routed through liquid metallurgical techniques

The Al2O3-SiC reinforced Al7075 Metal Matrix Composite (MMCs) is fabricated through liquid metallurgical technique. Ceramic particulates were amalgamated into aluminium alloy to achieve improved mechanical properties and wear resistance. Al-7075/Al2O3/SiC hybrid MMCs produced by reinforcing 2%, 3%, 4% 5% of Al2O3 7% SiC particles. Microstructural analysis was carried out evaluate the uniform dispersal within base matrix. output results indicate that enhanced increase wt. % ceramic particulates. Tensile fractography show internal fracture structure tensile test specimens in which pullouts observed. characteristics developed composites are studied using pin on disc apparatus. high resistance observed at + MMCs.
