| Abstract Scope |
The effect of Ag on the microstructure developed in Al-Cu-Ni-Mn alloys has been determined. In the as-cast condition, three phases were found and characterized by compositional differences rich in (1) Cu, (2) Ag, and (3) Ni. The compositions of the phases in the alloy may be related to the atomic radii of the elements in the phases. Static oxidation has been performed at 600, 700, 800, 900, and 1000°C for 24 hours in air. The oxides present on the surface were identified. The results have been compared with the microstructures affected by the addition of Si on the same quaternary alloy from a previous study. The silver-rich phase is an analog of the Mn-rich phase developed by the addition of Si in this alloy as reported previously by the authors. |
