Composite materials are increasingly prevalent both in industrial applications and in daily life in today’s world. Among composite materials, the most widely used type in industry is metal matrix composites, which are produced by incorporating one or more ceramic or metal reinforcing materials into a metallic matrix. Metal matrix composites are generally engineering materials with high strength and stiffness. In this category, Aluminium Matrix Composites (AMCs) stand out due to their combination of high strength, excellent corrosion and wear resistance, as well as low density and low cost. These properties have led to their increasing application in key sectors such as the automotive, aerospace, energy and defence industries. The production of Aluminium Matrix Composites is generally preferred by powder metallurgy as it allows the easy production of complex shaped materials, provides high density production, reduces costs, minimises material wastage and facilitates the mass production of materials with superior mechanical properties. In this study, B4C ceramic reinforcement particles were reinforced to AA2024 matrix powders at increasing wt% ratios and milled for 12 hours by mechanical alloying method using 2% Methanol as process control agent and composite samples were produced from the milled composite powders by hot pressing method. Accordingly, in the microstructure examinations of AA2024 matrix composite materials with increasing B4C ratios, a homogeneous distribution with low porosity was observed in the structure of the reinforcement particles by mechanical alloying, the hardness values of the produced composite materials were determined as 188.2 HB, 190.6 HB and 207.3 HB, and the tensile strength values of the composite materials were measured as 311.26 MPa, 324.81 MPa and 331.66 MPa respectively according to the increasing reinforcement ratios.
