Development of new damage tolerant alloys for age-forming
Development of new damage tolerant alloys for age-forming
The applicability of age forming for the forming of damage tolerant structures is investigated by formulating and testing new alloy-age forming combinations. The alloy formulation process is driven initially by modelling of strength and semi-quantitative understanding of other microstructure-property relations. Using this a range of Al-Cu-Mg-Li-(Zr-Mn) based alloys that are predicted to provide yield strengths in aged condition comparable with incumbent the 2024-T351 alloy for lower wing skins are selected. It is shown that several of these new alloys after artificial aging representative of age-forming have proof strengths (PS), fatigue crack growth resistance (FCGR) and toughness that are comparable or better than incumbent 2024-T351. UTS to PS ratios of the new alloys are lower than incumbent 2024-T351.

Abstract
The applicability of age forming for the forming of damage tolerant structures is investigated by formulating and testing new alloy-age forming combinations. The alloy formulation process is driven initially by modelling of strength and semi-quantitative understanding of other microstructure-property relations. Using this a range of Al-Cu-Mg-Li-(Zr-Mn) based alloys that are predicted to provide yield strengths in aged condition comparable with incumbent the 2024-T351 alloy for lower wing skins are selected. It is shown that several of these new alloys after artificial aging representative of age-forming have proof strengths (PS), fatigue crack growth resistance (FCGR) and toughness that are comparable or better than incumbent 2024-T351. UTS to PS ratios of the new alloys are lower than incumbent 2024-T351.
