摘要:
An aluminum-lithium alloy exhibiting good fracture toughness and relatively high strength has a nominal composition of 2.5 percent lithium, 1.0 percent magnesium, 1.6 percent copper, 0.12 percent zirconium with the balance being aluminium and trace elements.
摘要:
The combination of strength and fracture toughness, properties of aluminium-lithium alloys are significantly enhanced by underaging the alloys at temperatures ranging from 200°F to 300°F for relatively long periods of time.
