Mechanical and wear behaviour of 6351 Al/Gr/SiC composites fabricated by squeeze casting
2019
Abstract In this work hybrid 6351 Al/Gr/SiC composites are produced via squeeze casting using 6351 aluminium alloy as the matrix, with graphite and silicon carbide particles as reinforcements. The mechanical properties, viz., hardness and tensile strength of Al 6351 hybrid metal matrix composites are studied by conducting Vicker’s hardness test and tensile test, and wear tests are conducted to study the wear rate. The hardness and tensile strength are found to have increasing trend as the percentage of SiC increases and the percentage of Gr decreases. The wear rate of all composites has an increasing trend as the applied load increases.
