Özet

The present work reviews the toughening mechanisms and microstructural analyses of recycled hybrid metal matrix composites (aluminium based) reinforced with -alumina and pure recycled copper. This composite was manufactured by sintering and sinter + forging called the combined process. To analyze the mechanical / physical behavior of hybrid metal matrix composite materials; quasi-static compression, three-point bending (3PB), low velocity impact (dynamic compression) experiments were carried out. Additionally, wear and creep tests were conducted with a nanoindenter to evaluate the wear and time dependent behaviour of this composite. Evaluation of the microstructure of hybrid metal matrix composites wereperformed with Scanning Electron Microscope (SEM) supported by Energy Dispersive Spectrometer (EDS) analysis. The results showed that thecomposites have homogeneous structure without porosity and very homogeneous distribution of fine -alumina (Al2O3) and copper particles. Sinter + forging process yielded a material that had higher strength, hardness and better resistance to wear. This composite will be targeted for linkage applications where high toughness and high surface damage resistance is required.
