The high-pressure phase diagram at 5.4 GPa of Al-rich Al-Li alloy has been determined using the quenching method. The solid solubility of Li in Al was increased up to 20 at % and the eutectic temperature was raised up to 800°C. Variations of material properties (mainly elastic moduli) for obtained supersaturated solid solutions as a function of Li content have been determined. The shear modulus of the solid solutions increased at the rate of 0.28 GPa/at%Li, but the bulk modulus decreased 0.52 GPa/at%Li by contrast.
