Özet:

 In this study, the MgB_4C composite reinforced with boron carbide particles was produced by mechanical milling method using waste AZ91 magnesium alloy chips. The mechanical and tribological properties of the produced composites were investigated through hardness and wear tests. A mixture of AZ91 magnesium alloy chips, aluminum, and B_4C powders was milled at a rotation speed of 300 rpm with a ball-to-powder ratio of 20:1 for 3 hours. The milled powders were first cold pressed and then sintered at 550 C for 3 hours. In density measurement, it was observed that the sample reinforced with B4C exhibited an increase in density. In X-ray diffraction analysis, peaks corresponding to Mg, Mg_17Al_12, and MgO were detected, while the B_4C phase could not be identified. On the other hand, B_4C particles in the microstructure were revealed in the energy dispersive X-ray spectroscopy analysis. Scanning electron microscope images revealed that the MgB_4C composite had lower porosity, consistent with density measurements. It was found that the hardness and wear resistance of the MgB4C composite were higher than those of the Mg alloy, which can be attributed to the presence of homogenously distributed hard B4C particles within the microstructure.
