ABSTRACT:
This invention relates to the production of a useful eutectic layer formed on a zirconium alloy or a titanium alloy substrate. The layer is formed by the surface contact with a beryllium strip being held in intimate contact with the surface of the zirconium or titanium alloy substrate while the zirconium or titanium alloy and the contacting beryllium strip are heated in an inert atmosphere to a temperature which is above the eutectic melting point and is held constant at that temperature for a predetermined time. At the prescribed time, the materials are allowed to cool and the beryllium strip is "removed" from the "surface" of the zirconium or titanium alloy substrate and the newly formed zirconium-beryllium or titanium-beryllium alloy eutectic is formed in the surface of the zirconium or titanium alloy substrate.
