This study focuses on the development of a functionally graded composite material combining Al2024 and B4C materials. The composite was fabricated using powder metallurgy methods, incorporating mechanical alloying and hot-pressing techniques to achieve a graded structure. The mechanical alloying process was performed in a planetary ball mill at a rotation speed of 400 rpm, utilizing 10 mm tungsten carbide balls with a ball-to-powder weight ratio of 10:1. The composite structure was then consolidated through hot pressing at 560°C for 3 hours under an argon atmosphere, ensuring uniform densification. The resulting composite structure consists of four distinct layers, each with a thickness of 2.5 mm, yielding a total thickness of 10 mm and a cylindrical shape with a diameter of 40 mm. To characterize the composite, the morphological properties of the initial powders were examined using scanning electron microscopy (SEM), and particle size analysis was conducted to assess particle distribution and size uniformity. In addition, density measurements of the fabricated composite were obtained, and a detailed surface morphology analysis was carried out to evaluate the structural integrity and homogeneity across the graded layers. These comprehensive analyses provided valuable insights into the microstructural consistency and physical characteristics of the functionally graded composite. The cohesive mechanical and physical properties across the layers indicate that the Al2024-B4C composite may hold significant potential for advanced engineering applications, where gradual property transitions are beneficial for material performance.
