Analysing the mechanical and metallurgical behavior of aluminium 7075 composite with reinforcement of silicon carbide and zirconium oxide

Abstract

In today’s production industry, Aluminium Matrix Composites (AMCs) are the capable material.Because of their excellent mechanical qualities, they are widely employed in the aerospace, automobile, and naval industries.Strong ceramic particles, such as SiC, ZrO2, and others, strengthen the aluminium matrix, resulting in greater wear resistance and a better strength-to-weight ratio.Depending on the type of reinforcement, size, and morphology, AMCs can be manufactured in a assortment of methods.Traditional stir casting is a popular method for making AMCs meanwhile it is very reasonable and allows for a variety of materials and processing conditions. Using an indigenously designed stir casting technology, an attempt was made to produce Aluminium Matrix Composites (AA 7075) reinforced with SiC powder at various weight percentages.The homogeneous dispersion of SiC particles in the AMCs was verified by SEM morphology. Mechanical testing demonstrated that the tensile strength, wear resistance, Vickers hardness, and charpy tests all improved as the weight percentage of SiC particles increased.
