© 2021, The Society for Experimental Mechanics, Inc.The copper-aluminium (Cu-Al-Zn) based structures show shape memory behaviours that are low cost engineering applications, such as actuators, valves, etc., regarding to Ni-Ti-Al structures. These alloys have a useful transformation temperature that can be modified to lie between −100 and 100 °C. For a low cost production, a combined method through powder metallurgy processes (sinter-Forging) have been performed for the production the composite called “Zn-Cu-Al-1X” with addition of small amount of reinforcements. For two basic production methods, sintered-forging process have been carried out at the temperature of 550 °C and 650 °C with 1 h dwell time followed slow quenching and final cooling operation respectively. In the frame of the common research project, production of the scrap thin sheet copper based composites reinforced with pure nano aluminium (~5 wt %) and fine zinc particles were produced with addition of small amount of fine particles as secondary reinforcements. These composites will be used for the applications of the coupling and actuators in the aeronautical area. For mechanical basically for the tailored behaviour of this composite, three point bending (3 PB) and impact tests were performed. Microstructural analyses was carried out with Scanning Electron Microscopy (SEM). Ductility and tailored behaviour of this composite will be discussed through the toughness mechanism depending on the processing parameters.
