Exploring alloying effect on phase stability and mechanical properties ofγ″-Ni3Nb precipitates with first-principles calculations

The superior mechanical strength of Inconel 718 and similar Nb containing alloys mainly results from the ordered γ″-Ni3Nb precipitates. By employing first-principles calculations, we comprehensively investigate the effects of alloying elements (i.e., Sc, Ti, V, Cr, Mn, Fe, Co, Y, Zr, Mo, Tc, Ru, Rh,...
