Abstract

The compression characteristic of an (AL-4% CU) alloy reinforced with different particles (boron carbide, silicon carbide, and titanium carbide) was numerically studied. For this purpose, a model was performed using COMSOL Multiphysics 4.1. Hence, three samples were selected and reinforced with carbide particles equal to 20 microns’ in diameter and then compared with that one not reinforced. An axial load of 20 Newton was applied for all samples from both sides. The results showed that the alloy (AL-4% CU) reinforced with boron carbide particles has the highest compressive resistance compared to the other reinforced particles. The elongation of boron carbide, silicon carbide and titanium carbide particles were 1x10−7mm, (1.3*10−7 mm) and (1.5*10−7 mm) respectively, while it was (5.5*10−8 mm) for not unreinforced particles.
