  • Mechanically alloyed dispersion strengthened aluminum-lithium alloy
    Patent number: 4532106
    Abstract: A dispersion-strengthened aluminum-base alloy system is provided which is prepared by mechanical alloying and is characterized by high strength, high elastic modulus, low density and high corrosion resistance. The alloy system is comprised, by weight, of at least above 1.5% up to about 3% Li, about 0.4% up to about 1.5% O, about 0.25% up to about 1.2% C, and the balance essentially Al.

  • Process for making alloys having coarse, elongated grain structure
    Patent number: 4497669
    Abstract: An alloy made by water atomizing the charge component into powder, extruding the powder, hot rolling the powder and heat treating the product. The alloy displays superior stress rupture characteristics when compared to a corresponding conventionally wrought alloy.
