Abstract
Abstract Alloys reacting with water, water vapor and reactive gases at temperatures in the range of about 200° to about 650° C. have the essential components of nickel, titanium and zirconium. The alloys can be made by arc melting zirconium, nickel and titanium and can be formed into sheet or foil by inert-atmosphere hot rolling. The alloys can also be made by plating nickel on a sheet of zirconium-titanium alloy and then conducting a diffusion process by heating the plated alloy in vacuum.
