In this study, the toughening mechanism of pure electrolytic copper-based composites reinforced with Boron Carbide ceramic particles (B4C), NiAl intermetallic compounds and recycled with atomized pure aluminium powder (AA7075) have been studied by using static and dynamic compression tests. Cyclic stress relaxation tests were also carried out after treated of the specimens under different air conditions (humidity, temperature, etc.). It is aimed to be an alternative to traditional alloys/composites used in the aeronautical industry. These composites are generally produced using by combined sinter + forging processes. Microstructure analyses were carried out by Scanning Electron Microscopy (SEM) microstructures.
