| Abstract Scope |
Al-Cu-Ni-Mn and Al-Cu-Ni-Mn-Si high entropy alloys have been made in equi-atomic proportions. Both alloys were exposed to oxidation in air for 24 hours at 600, 700, 800, 900, and 1000OC. The as received and oxidized microstructure of the alloys have been characterized using a scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), and x-ray diffraction (XRD). Three phases have been identified in each alloy in the as received condition. Both alloys contain a Ni rich phase and a Mn rich phase. The quaternary alloy has a phase rich in Al-Cu-Ni and the quinary alloy has a phase rich in Al-Cu-Mn. Oxides and intermetallics have also been recognized after oxidation at each temperature, respectively. |
