Tensile and Hardness behaviour of AlMg1SiCu alloy reinforced with SiC/ MoS2 metal matrix composite

Abstract

The current work examines the AlMg1SiCu alloy material through the stir casting process, where the Molybdenum Disulphide (MoS2 ) using three different variations of weight percentage (3 MoS2%, 6% MoS2, 9% MoS2) and 10% uniform proportion silicon carbide (SiC). The distribution of reinforcements such as Hard particle Silicon Carbide (SiC) and Soft particleMolybdenum Disulphide in the matrix was studied by looking at the microstructure of the composites before Tensile and Hardness test using Backscattered Secondary Electron image (BSE). A Brinell hardness tester was employed to determine the hardness of samples made of AlMg1SiCu alloy and hybrid metal matrix composites. Tensile test carried out using a Universal test Machine for AlMg1SiCu alloy and HMMC Samples. With an increase in MoS2 particle percentage, hybrid composites' tensile strength improves. With a AlMg1SiCu hybrid composite containing 10% SiC and 9% MoS2, the maximum tensile strength has been achieved.
