Mechanical behavior of aluminium based stir casted composite materials utilizing petroleum waste, ceramic powder and metal powder as the reinforcement

Abstract

Hybrid composites are substances created by fusing two or more distinct fiber types together in a single matrix. The current research focuses on the manufacturing of a hybrid metal matrix composites in which aluminium 5083 alloy serving as the matrix material and nanoscale boron carbide (B4C), a petroleum waste spent alumina catalyst (SAC) and nickel (Ni) powder serving as the reinforcements, the aim of this work is to create, improve, and characterize hybrid metal matrix-reinforced composites. The hybrid composite was fabricated through stir casting method. There was less porosity was found in the hybrid composite when the specimens were observed through the optical microscope. Hybrid composites with aluminum matrix (6 % boron carbide, 2 % SAC and 6 % Nickel powder reinforcement) have a high degree of hardness and high engineering skills. The maximum tensile strength of the composite, which included 4 % B4C, 4 % SAC, and 6 % Ni powder found to be 245 N/mm2.
