International Classification:
H01M 458
US Classification:
4292182, 296231, 429 60
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 10 Â C. per second.

International Classification:
C22C 3302
US Classification:
75246
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.
