Review on Corrosion Behavior, Fatigue Behavior and Fracture Toughness of AL Alloy MMCS

Abstract

In order to improve fuel efficiency, structural materials like Aluminium Alloy Metal Matrix Composites (MMCs) with high specific strengths are currently looked for. These materials are mostly used in the automobile and aircraft industries. In order to increase the elastic modulus, wear resistance, corrosion resistance, and fracture toughness of composite materials, researchers have attempted to choose reinforcements for composites effectively.Numerous physical and mechanical tests are important due to the constantly rising performance requirements in different applications. In order to describe and comprehend the performance of these materials, testing of composites is necessary. Tensile, compression, impact, bend, shear, corrosion, fatigue, and fracture toughness tests are among the experimental procedures used to test composite materials.Among the above mechanical testings, this paper aims to review and analyse a wide range of corrosion and fatigue behaviours with various types of reinforcements in aluminium alloy MMCs as these tests are significant in service life and performance aspects. In this paper efforts are made in order to understand how the trend evolves along with the reinforcements used and the technique followed.
