An evaluation is made of the supply sources and current availability of elements involved in superalloy compositions, as well as of development trends in the substitution of strategic materials for superalloys, giving attention to the results thus far achieved by NASA's Conservation of Strategic Aerospace Materials program, which formally operated only from 1980 to 1984 but whose various research initiatives have been continued under other NASA programs. Peacetime and wartime economies' need and probable availability analyses are presented for bauxite/aluminum, the Pt-group metals, and the alloying elements Mn, Nb, Ta, Co, Cr, Ni, W, Fe, Cu, Ti, Mo, and Mg.
