Production of AA2024-Matrix B4C-SiC- and B4C-Y2O3-Particle-Reinforced Composites by Powder Metallurgy and Investigation of Their Mechanical Properties

Abstract

In this study, it was aimed to produce Al-matrix composite materials with B4C-SiC and B4C-Y2O3 particle reinforcement using the Powder Metallurgy (PM) method. In the composites in which the reinforcement materials were used at different particle sizes and ratios, AA2024 powders were selected as the matrix material. The powders were homogeneously mixed and compacted at room temperature under a pressure of 525 MPa. The raw specimens were sintered by keeping them at different temperatures for 45 minutes. The composite materials were subjected to wear tests, and their hardness and density values were investigated. In the study, the effects of reinforcement materials added to the matrix at different particle sizes and ratios on wear resistance, hardness, and density at different temperatures were examined.
