In this study, graphene nanoplatelets (GNPs) and boron carbide (B₄C) nano reinforcements were incorporated to the pure magnesium (Mg). Powder metallurgy route was used to fabricate composite samples. Microstructures of specimens were examined and tensile, hardness, wear tests were performed to determine the mechanical and tribological performance of produced samples. The results indicate that the hardness was increased especially with the addition of 2% B₄C and 0.5% GNPs reinforcements. A general trend was observed for the enhancements of yield and tensile strengths when nano reinforcements were added to the pure magnesium. The composite samples showed better wear resistance than the unreinforced sample. However, thermal conductivity began to decrease with the addition of B₄C reinforcements. It is also observed that the porosity level was also higher for the composite samples.

在这项研究中，石墨烯纳米片 (GNP) 和碳化硼 (B ₄ C) 纳米增强材料被结合到纯镁 (Mg) 中。粉末冶金路线用于制造复合样品。检查试样的微观结构，并进行拉伸、硬度、磨损试验，以确定生产的试样的机械和摩擦学性能。结果表明，特别是加入 2% B ₄ C 和 0.5% GNPs 增强剂后，硬度增加。当将纳米增强剂添加到纯镁中时，观察到屈服强度和抗拉强度提高的一般趋势。复合材料样品显示出比未增强样品更好的耐磨性。但随着 B 的加入，热导率开始下降₄ C 增援。还观察到复合样品的孔隙率水平也更高。
