Abstract

In this work, a special copper aluminium matrix composite (ACMMCs) obtained from the fresh scrap – chips of AA7075 and- pure electrolytic copper were designed through combined method of powder metallurgy and sinter + Forging. First of all, Al-Cu matrix was doped with ZnO after the ball milling with two basic reinforcements (Nb2Al– SiC, etc.) was carried out during the 4 h. A basic composition was prepared depending on the doping percentage of ZnO as 30 wt%. Mechanical and physical properties of this composite designed here can be improved with the doping process followed by combined method of powder compacted specimens and doping volume fractions. The surface scratch tests and micro-hardness results were compared according to the optimization conditions of the doping and the reinforcement. Static compression and impact-drop weight tests were carried out. The microstructure and damage analyses have been carried out by Scanning Electron Microscope (SEM).
