Using θ′ interfaces as templates for planar L12 precipitation in AlCuMnZr alloys

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 formation stabilizes θ' most effectively; ho...
