초록
In this study, Boroncarbide (B4C) powders were added as supplemental material to produce aluminum (Al) metal matrixcomposites (MMC) by mechanical alloying (MA) method. Three different B4C amount (5, 7,5, and 10 wt%) were used andthree different temperatures (600, 620, and 640 oC) were applied for the sintering of the samples. Wear rate, hardness, anddensity of the produced composites were evaluated in order to investigate the effect of different B4C content and sinteringtemperatures. It was found that the increase in the B4C amount decreased the wear rate and density of the specimens whileincreasing the hardness. Moreover, the application of different temperatures had a positive effect on the density, hardness, andwear behavior of the specimens.
