It is known that very large quantities (30-50 AT percent) of inert gas, He, Ne, Ar, Kr and Xe, can be incorporated into metal alloys of various transition elements (e.g., Co and Mo) with various rare earth elements (e.g., Gd) formed in an amorphous state by sputter deposition. Moreover, the gas stays in this metal alloy for indefinite periods until the metal is heat to it recrystallization temperature (T(c) approximately 9OO degrees C for Gd-Co-Mo), which point all this inert gas is rapidly released. The volume of gas released is several thousand times the volume of metal alloy. The metal alloy has mechanical corrosion properties suitable for use in structural applications and need not be too expensive if a mixture of rare earth elements, known as misch metal, is used.
