Abstract: A master alloy comprising vanadium, nickel and chromium having equal weight percentages of vanadium and nickel and from about 4% by weight to about 17% by weight of the total weight, of chromium is used to prepare alloys having those metals and other metals selected from the group consisting of zirconium, titanium, cobalt, manganese, aluminum and mixtures thereof.

Abstract: A hydrogen battery alloy is prepared which is substantially free of inclusions of chromium by preparing a first precursor alloy or master alloy containing vanadium, nickel, and chromium using relatively equal amounts of vanadium and nickel and then adding from 5% to 12% by weight of chromium. The alloy materials are introduced into an aluminothermic reaction as vanadium pentoxide, nickel powder and chromium powder with the aluminum metal being in slight excess of its stoichiometric amount. The first precursor alloy described further alloyed with preselected amounts of nickel, zirconium, titanium, cobalt, manganese, aluminum, and chromium to form an alloy suitable for use as an electrode material in rechargeable electrochemical hydrogen storage cells.

Abstract: A nickel-titanium-palladium based alloy for converting heat energy into mechanical energy. The alloy exhibits shape memory. The alloy contains palladium to raise the temperature at which the alloy flexes between a deformed condition at a relatively colder temperature and a nondeformed condition at a relatively higher temperature. The alloy is characterized by including boron for increasing the fabricability of the alloy.
