Friction stir processing (FSP) is a metal-working technique that causes microstructural modification and change in the upper surface of metal components. In this work the effects of tool pin profile on the microstructure and mechanical behavior of reinforced SiC particles metal matrix composites (MMCs) produced by friction stir processing were studied. Optical microscopy (OM) and Scanning electron microscopy (SEM) was employed to carry out the microstructural observations. Vickers Microhardness Machine used for microhardness evaluation. Results show that, tool pin profile play a major role in improvement of the surface quality, SiC particles dispersion in pure copper matrix, hardness behavior and wear resistance. Two different tool pin profile (straight cylindrical and square) were used to perform the process. It was found that, straight cylindrical tool pin profile led to finer grains, uniform dispersion of SiC particles, higher microhardness and wear resistance values.

Friction stir processing (FSP) was used to fabricate Al/Cu metal matrix composite (MMC). The effects of two different tool pin profiles (straight cylindrical and square) and the number of FSP passes on microstructure, tensile properties and microhardness were studied. The results indicated that good dispersion of micro-sized Cu particles, finer grains, higher tensile properties and higher microhardness, can be achieved by the square tool pin profile compared to the samples produced by the other tool. Also it was observed that the ultimate tensile strength of the samples produced by two FSP passes, as a result of Cu particles shattering, increased intensively compared to the samples fabricated with first FSP pass. Further FSP passes increased the elongation of the composites without any considerable changes in yield and ultimate tensile strength.
