Abstract: A rapidly solidified, low density aluminum base alloy consists essentially of the formula: AlbalLiaCubMgcZrd wherein 'a' ranges from about 2.2 to 2.5 wt%, 'b' ranges from about 0.8 to 1.2 wt%, 'c' ranges from about 0.4 to 0.6 wt% and 'd' ranges from about 0.4 to 0.8 wt%, the balance being aluminum plus incidental impurities. The alloy is especially suited to be consolidated to produce a strong, tough, low density aircraft landing wheel.

Abstract: A component consolidated from a rapidly solidified aluminum-lithium alloy containing copper, magnesium and zirconium is subjected to a preliminary aging treatment at a temperature of about 400 DEG C to 500 DEG C for a time period of about 0.5 to 10 hours; quenched in a fluid bath; and subjected to a final aging treatment at a temperature of about 100 DEG C to 250 DEG C for a time period ranging up to about 40 hours. The component exhibits increased strength and elongation, and is especially suited for use in lightweight structural parts for land vehicles and aerospace applications.

Abstract: A rapidly solidified zirconium containing aluminum lithium alloy powder consisting essentially of the formula AlbalLiaCubMgcZrd where "a" ranges from 2.1 to 3.4 wt %, "b" ranges from about 0.5 to 2.0 wt %, "c" ranges from 0.2 to 2.0 wt % and "d" ranges from greater than about 0.6 to 1.8 wt %, the balance being aluminum. The powder is degassed in a vacuum at a temperature of at least about 450 DEG C. Components consolidated from the powder exhibit high tensile strength and elongation together with excellent notched impact toughness.

Abstract: A component composed of a rapidly solidified aluminum-lithium alloy is subjected to thermal treatment at a temperature greater than 500 °C for a time period greater than 5 hours under a protective atmosphere. Thus case toughened, the component exhibits notched impact toughness from 40 to 250 % greater than that exhibited prior to the thermal treatment.
