Impact of Boron Carbide Particles and Weight Percentage on the Mechanical and Wear Characterization of Al2011 Alloy Metal Composites

Micron-sized B₄C addition to the Al2011 alloy was investigated for its impact on mechanical and wear performance. The stir-casting method was used to manufacture the Al2011 alloy metal matrix composites reinforced with varying percentages of B₄C particulates (2, 4, and 6). The microstructural, mechanical, and wear properties of the synthesized composites were tested. scanning electronic microscope (SEM) microscopy and XRD patterns were used to characterize the microstructure of the samples that were obtained. The XRD patterns confirmed the presence of B₄C particles. The addition of B₄C reinforcement increased the metal composite's hardness, tensile strength, and compressive strength. Incorporating the reinforcement resulted in a decrease in elongation for the Al2011 alloy composite. The wear behavior of the prepared samples was examined under various load and speed conditions. In terms of wear resistance, the microcomposites were far superior. SEM observations of the Al2011-B₄C composites revealed numerous fracture and wear mechanisms.
