Mechanical Behavior of Aluminum Based Mattel Matrix Composites

Abstract

The mechanical behavior of aluminum-based metal matrix composites (AMMC) has been a subject of significant research and interest in the field of materials science and engineering. These composites, composed of an aluminum matrix reinforced with other materials, exhibit unique mechanical properties compared to traditional aluminum alloys. This abstract provides a concise overview of the key aspects of the mechanical behavior of AMMC. Fatigue resistance, a critical aspect for materials subjected to cyclic loading, is influenced by the type of reinforcement, particle size, and the matrix-reinforcement interface. Proper dispersion of the reinforcement particles contributes to enhanced fatigue life. AMMCs also demonstrate improved wear resistance compared to the base aluminum alloy, making them suitable for applications where wear is a significant concern. Thermal properties, including thermal conductivity, are influenced by the type and volume fraction of the reinforcement. The processing techniques used, such as powder metallurgy or stir casting, play a crucial role in determining the final mechanical properties of AMMC Understanding the temperature dependence of AMMC is essential, considering their potential applications in diverse environments. Ongoing research in this field aims to further optimize the mechanical behavior of these composites for applications in aerospace, automotive, and structural engineering.
