Influence of B4C and industrial waste fly ash reinforcement particles on the micro structural characteristics and mechanical behavior of aluminium (Al–Mg–Si-T6) hybrid metal matrix composite

The expectations over composite materials have been increased especially in automotive and aerospace applications due to its high strength weight ratio good mechanical properties. Here, we aim fabricate a hybrid of low density for application suits the above needs. In this investigation, heat-treated aluminum alloy Al–Mg–Si-T6 was initially reinforced with industrial waste fly ash particles at five different fractions 0%, 5%, 10%, 15% 20%, respectively by stir casting process. properties such as tensile strength, compression hardness were tested, microstructure evaluated explain evolution. From results, it concluded that 10% shows enhanced maximum when compared others. Then, – 5% further boron carbide using three 2.5%, 7.5%, microstructural analysis, Scanning Electron Microscope analysis (SEM) Energy Dispersive X-ray Spectroscopy (EDS) carried out casted samples evaluate interfacial bonding, agglomeration, clustering void formation samples. also tested density. It reveals optimal combination reinforcement (5% carbide) 18.7% higher 11.3% 38.6% unreinforced heat treated alloy. is expected present metal matrix composites can be adopted fabrication drive shaft race cars.
