A Review on Effect of Processing Parameters on Mechanical Properties of MMCs by Friction Stir Process

The current investigation is aimed to give a thorough explanation of metal matrix composite fabrication by taking different combinations of the reinforcements by using the principles of friction stir technique and impact of the input processing parameters on mechanical properties done by the different researchers. The researchers attempted to actuate a relation between the input process parameters and their output responses. Friction stir welding and processing method uses significantly less energy. For many engineering applications the metal matrix composites replaces the regular used materials because of its unique mechanical and metallurgical properties, stability, durability, resistance to corrosion. The process parameters includes rotational speed, tilt angle, feed and deposition rate have major impact on mechanical properties of fabricated composite surfaces by the friction stir process. The solid state nature of processing method is brought out the enhancement in different properties in surface composites. The pin profile is also having major impact on mechanical properties. The different pin profile generally used are triangular, cylindrical, hexagonal and pentagon. The present study can give a concept of defect free weld having higher and improved mechanical properties on surface composites.
