Friction Stir Processing (FSP) is a new solid-state processing technique for micro structural modification which was developed based on the principle of Friction Stir Welding (FSW). The basic concept of FSP is remarkably simple. A non-consumable rotating tool with a pin and shoulder is inserted into a single piece of material and traversed along the desired path for localized micro structural modification for specific property enhancement in the processed zone due to intense plastic deformation, mixing and thermal exposure of material. Friction Stir Processing (FSP) is a solid–state surface modification technique to alter the properties of metals and alloys. This work studies the effect of FSP on pure copper with three different tool pin profiles (plain cylindrical, square and taper ) at low-heat input condition. The tool rotational speed and tool traverse speed were kept constant to maintain the low heat input., micro hardness and tensile strength were analyzed to evaluate the modifications occurred in the mechanical properties.
