This process provides a method of fabricating porous aluminide articles. First the process consists of plating a preform with nickel and aluminum to create a metal-plated structure. The plating of nickel consists of electrodeposition or gaseous plating. The plating of aluminum consists of gaseous deposition of an organometallic-aluminum compound. The preform has either an open felt, woven fabric or a reticulated foam shape. Reactive sintering the metal-plated structure leaves an open nickel-aluminum structure having porosity and excellent strength and oxidation properties above 400.degree. C.
