High molybdenum, corrosion-resistant alloys are provided with greatly increased thermal stability by controlling the atom concentrations to be NiaMobXcYdZe, where:a is between about 73 and 77 atom percentb is between about 18 and 23 atom percentX is one or more required substitutional alloying elements selected from Groups VI, VII and VIII of the Periodic Table and c does not exceed about 5 atom percent for any one element,Y is one or more optional substitutional alloying elements which may be present and d does not exceed about one atom percent for any one element,Z is one or more interstitial elements and e is as low as possible, not exceeding about 0.2 atom percent in total;and the sum of c and d is between about 2.5 and 7.5 atom percent.
