Fabrication of the Composites (AA6082-T6/SiC) by Using Friction Stir Processing

Abstract

In this paper, a study of the microhardness of aluminum metal matrix composites has been carried out, i.e., AA6082-T6/SiC composites were fabricated using friction stir processing technique. There is a great demand for reduction of weight of the material used in manufacturing in aerospace and automobile industries. It shows that most of the industries give more importance to increase the strength-to-weight ratio. A number of research scholars are working on this to find out the best material. Metals like aluminum, copper, magnesium, etc., are found out, but these are having very low strength. These metals cannot be used directly, but there is a unique method of processing which should be done and then converts it into metal matrix composite. In stir casting process, we reinforce the particles after melting of metal and distribution of particles in metal matrix is very difficult. There is a reaction which takes place between reinforcement and metal matrix. So, uniform distribution of particles is not taking place properly. A number of other techniques also find out to make unique technique using Taguchi Approach L-27 orthogonal array. The four process parameters are considered to analyze the microhardness of these composites. In this analysis, Minitab software was used.
