... of niobium alloys are given in Table 31.2 . Solid-solution strengthening is greatest for alloying elements that have a large atomic size misfit, a low diffusivity, and a high melting point (for thermal stability). Substitutional alloying additions include tungsten, molybdenum, tantalum, and vanadium...
