Controlled Mn and Zr additions to Al-Cu alloys have allowed for the improved retention of mechanical properties after extended 350°C exposures by stabilizing the main strengthening θ' (Al2Cu) phase. Ultimately, θ'/L12 (Al3Zr) co-precipitate format

The effects of adding 0.08 at.% Cr or 1 at.% Zn to a dilute Al-0.11Zr-0.005Er-0.02Si at.% alloy are studied in terms of the precipitation behavior of Al3Zr (L12-structure) nanoprecipitates and the resulting alloy's creep resistance. Although Cr and Z

Dilute Al Sc alloys ( Ni alloys (Al-6 wt.% Ni) derive their high strength at elevated temperature from Al3Ni microfibers formed during solidification. Here, we investigate ternary Al 6Ni-0.2Sc and Al 6Ni-0.4Sc alloys with both types of strengthening
