This paper examines the effects of various additions to binary Al-3Li on electron-beam weld solidification structures and tensile properties. These additions include Zr for grain refinement, Mg for solid solution strengthening, Cu for precipitation strengthening, and Co for dispersion strengthening. Aluminum-lithium alloys containing 3 wt% lithium are candidates to replace commercial 2xxx and 7xxx aluminum alloys in structural applications.
