Fabrication and analysis of LM13/B4C/Gr hybrid metal matrix composites

Due to mechanical characteristics like light weight nature, enhanced wear resistance, greater strength to wear ratio, stiffness, and better electrical and thermal properties, Aluminium (Al) matrix composites are deployed in military, automotive and aerospace areas. Frequently utilized ceramic elements for reinforcing with Al are alumina and silicon carbide (SiC). Boron carbide (B4C) is an excellent reinforcement substance having a higher hardness than other substances. Because of its substantial hardness, B4C can be used as a substitute to alumina and SiC. In addition to its superior hardness, modest density, greater strength, better chemical stability, and wear resistance are diverse appealing characteristics of B4C. So, for boosting the properties of the LM13/Gr composite samples, B4C is added up to 9% by considering its clustering property. This article describes the production process of LM13/B4C/Gr composites and evaluation of their mechanical characteristics. Stir casting method is adopted to produce the Al composite samples and the mechanical properties of new hybrid composites are found improved.
