The concept of reuse and recycling has undergone sustained development in industries to prevent the exhaustion of naturally available resources. The current study is about reusing spent catalyst waste from petroleum refining industries as reinforcement in aluminum composite materials. This work utilized the stir casting method to create nano B 4 C/waste spent catalyst/Al matrix composites by varying the B 4 C from 0.5 to 2.0 wt% and maintaining the constant 10 wt% of spent catalyst waste, respectively. Furthermore, the impact of nano B 4 C and spent catalyst waste on the mechanical and microstructure behavior of aluminum matrix hybrid composites were studied. The compressive strength, hardness, and tensile strength of the aluminum composites obtained with different percentages of nano B 4 C and spent catalyst waste were enhanced significantly. The increase in tensile strength mainly due to the effect of the Orowan strengthening mechanism and thermal stresses caused by the difference in the CTE of aluminum matrix and reinforcement. The effective mechanical behavior was obtained with 1.5 wt% B 4 C and 10 wt% spent catalyst waste with massive improvements in hardness (65.62%), compressive (31.81%), and tensile strength (48.23%), respectively, compared to base pure aluminum.
