A review on fabrication and mechanical characterization of high-strength 7xxx series aluminum alloys reinforced with ceramic reinforcements
Aluminum alloys of the 7xxx family have found widespread usage in a broad variety of technical applications in recent years. Aluminum matrix composites are being used in greater quantities across a variety of industries, including aerospace and military, as well as the automotive industry. The strength-to-weight ratio, strength, stiffness, and hardness of components made of aluminum-based composites are higher than those of monolithic materials, and they also exhibit better tribological behavior. Composite materials could include these characteristics. The properties of aluminum matrix composites for bearing components heavily depend on the best choice of the reinforcing material and the production process. As a result, alloys made of Al 7xxx are the most essential materials for structural use. In this current study, the development trend and impact of reinforcements on Al 7xxx alloys for engineering applications are presented, and the existing issues are described in a concise manner.
