<p>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 °C. Components consolidated from the powder exhibit high tensile strength and elongation together with excellent notched impact toughness.</p> |
