  • Electrochemical hydrogen storage alloys for nickel metal hydride batteries, fuel cells and methods of manufacturing same
    Patent number: 6500583
    Abstract: Practice of this invention provides, at least, a method of making a hydrogen storage material comprising the steps of: 1. forming a molten mixture comprising nickel and at least one other transition metal element, the combination of which will form a TiNi alloy and including in said molten mixture from about 0.1 at. % to about 10 at. % of one or more elements which will form an alloy which is immiscible in the TiNi-type alloy; and (b) cooling said molten mixture to form a solid alloy-system material by rapid solidification of said molten mixture at a cooling rate of at least 103° C. per second.

  • Method for compacting high alloy steel particles
    Patent number: 6099796
    Abstract: A method for producing compacted, fully dense articles from atomized tool steel alloy particles by placing the particles in a deformable container, and isostatically pressing the particles at an elevated temperature to produce a precompact having an intermediate density. The precompact is heated to a temperature above the elevated temperature used to produce the precompact. The precompact is isostatically pressed to produce the fully-dense article.
    Type: Grant

    Assignee: Crucible Materials Corp.
    Inventors: William B. Eisen, Walter Haswell, Kenneth J. Wojslaw, Jeryl K. Wright
  • Method for compacting high alloy tool steel particles
    Patent number: 5976459
    Abstract: A method for producing compacted, fully dense articles from atomized tool steel alloy particles by placing the particles in an evacuated, deformable container, and isostatically pressing the particles at an elevated temperature to produce a precompact having an intermediate density. The precompact is heated to a temperature above the elevated temperature used to produce the precompact. The precompact is isostatically pressed to produce the fully-dense article.

  • High strength, corrosion resistant austenitic stainless steel and consolidated article
    Patent number: 5841046
    Abstract: A consolidated, fully dense, high yield strength, austenitic stainless steel and article produced therefrom having improved pitting resistance and a low sigma solvus temperature. The article is produced from nitrogen gas atomized prealloyed particles. The steel and article have a high nitrogen content for increased strength and corrosion resistance.
