Microstructure and Mechanical Properties of an Al-Cu-Mg-Fe-Ni Alloy
The microstructure and mechanical properties of the Al-2.24Cu-1.42Mg-0.9Fe-0.9Ni alloy were studied using optical microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and tensile tests. The results indicate that the microstructures of the as cast alloy involve α-Al matrix, Al/Al2CuMg eutectic structure, Al7Cu2Fe, Al7Cu4Ni and Al9FeNi compounds. The tensile test results indicate that the alloy at elevated temperature (200°C) displays superior tensile strength due to the presence of the thermally stable Al7Cu2Fe, Al7Cu4Ni and Al9FeNi compounds.
