Abstract


Background/Objectives: In recent days, the demand of light-weight materials is being increased in industrial applications. Especially, nanocomposites are used in aerospace, automobile sector and bio-medical applications. Methods/Statistical Analysis: In this context, in the current study, aluminium alloy - boron carbide composites were fabricated and its microstructure analysis was evaluated with the help of Optical Microscope (OP). Further, a detailed study was done to evaluate the mechanical and wear resistance of the fabricated composites. Findings: The OP pictures reveal that boron carbide particles were uniformly distributed in aluminium matrix. When the amount of boron carbide is increased, the density of the composites is decreased which resulted 1. The micro hardness is increased. 2. The ultimate compressive strength is also increased and 3. Wear resistance is also increased. Application/Improvements: This study proves that the aluminium reinforced with Boron Carbide composite exhibits better performance than aluminium AL1100 in all aspects. Hence, aluminium reinforced with Boron Carbide composite can be used in aerospace applications.
