material and traversed along the desired path to cover the region of interest. Friction between the shoulder and workpiece results in localized heating which raises the temperature of the material to the range where it is plastically deformed. During this process, the severe plastic deformation and thermal
exposure of material, results in a significant evolution in the local microstructure. FSP has been successfully used for formation of nanograin, increase the surface hardness and also enhances the wear resistance, tensile strength and fatigue strength of the material. This review paper, the current
scenario and development of FSP of various materials mainly (a) formation of nanograins, microstructure and mechanical properties. (b) Effect of FSP/W process parameters.

The results showed that the grain size of fabricated composite reduce, also it is indicated that in comparison to base metal (copper) micro hardness of friction stir processed composites in stir zone (SZ) increase significantly. The results obtained also indicated that the selected FSP parameters significantly influence the area of surface composite by the distribution of material particles.
Higher tool rotational speed and lower processing speed produce an excellent distribution of material particles and higher area of surface composite due to higher frictional heat, increased stirring and material transportation.

It is also unique from
the viewpoint of its applicability to a localized region. Here the states of development of FSP for processing of Copper with carbon nanotubes are addressed. This paper investigates the parameters affecting the friction stir processed copper with carbon nano tubes and enhancement of the microstructure, hardness and tensile properties of the composite material. The
behaviour of Copper with carbon nano tubes has been studied with single pass, double passes and triple passes. The SEM results are also presented for each case.

All such studies have been considered and a detailed review is presented in this paper. Results indicated friction stir welding / processing with aluminium and alloys may successfully utilised, because of the significantly improved strength in the
material and at the same time the ductility also retained, along with the substantiallyimproved hardness. FSP was found to be beneficial also in improving wear resistance.

friction stir processed copper and enhancement of the
mechanical properties of the composite material studied by
various researchers. The effect of friction stir processing (FSP)
parameters such as tool rotational speed, processing speed, axial
load, groove width and depth, investigated change in
microstructure, micro hardness, tensile strength and wear
resistance have been discussed. The results showed that the grain
size of fabricated composite reduce, also it is indicated that in
comparison to base metal (copper) micro hardness of friction stir
processed composites in stir zone (SZ) increase significantly. The
results obtained also indicated that the selected FSP parameters
significantly influence the area of surface composite by the
distribution of material particles. Higher tool rotational speed
and lower processing speed produce an excellent distribution of
material particles and higher area of surface composite due to
higher frictional heat, increased stirring and material
transportation.
