In this study, the production and mechanical properties of porous metal matrix composites (MMC's) by recycling of spheroid cast iron chips (GGG-40) and bronze chips (CuSn10) by hot isostatic pressing was investigated. The metal matrix composites were produced with four different CuSn10 contents, three different pressures and temperatures and effects of production parameters on porosity, hardness, flexure properties were examined. Samples were produced in prismatic shape with specified porosity. The mechanical properties were determined by Brinell and Micro Vickers hardness tests and three-point bending test. The consolidation mechanism of metallic chips was also investigated with optic microscopy. It was examined whether any second phase occurred between metallic chips by the help of XRD test. As a result of porosity test, it is found that metal matrix composites can have porosity value of as much as 20%. It is also showed that owing to excessive plastic deformation of Cu Sn10, the hardness of MMC material can be higher than bulk CuSn10. Three-point bending test showed that the flexure properties of MMC materials are is lower than that of bulk CuSn10. As a consequence, it showed that metallic chips were recycled with hot pressing successfully.
