Abstract

We characterize novel metal carbon materials called covetics. More specifically we study a warm-rolled aluminum alloy (Al 7075) with up to 5 wt% of carbon infused during processing. At the macroscale, we measured mechanical properties: Young's modulus, ultimate tensile strength (UTS), 0.2% yield strength (YS), and tensile elongation at failure. At the mesoscale, we measured Rockwell and Vickers hardness, and, at the microscale, we measured local elastic modulus and hardness using a nanoindentation technique. In parallel, we characterized the microstructure of these materials at different structural scales using scanning electron microscopy (SEM) and transmision electron microscopy (TEM). The following enhancements in properties over the corresponding base materials were observed: 1. higher strength (UTS, YS) 2. higher hardness (Rockwell, Vickers and nanoindentation) 3. larger elongation, and 4. lower density, as carbon content increased. In summary, the results show that Al 7075 covetics exhibit superior mechanical properties to the corresponding base metals, which makes them very good candidates for range of engineering applications.
