AbstractThe site occupancy, lattice misfit and elastic modulus of Ni-based single crystal superalloys are investigated by combining the first principles exact muffin-tin orbital method and coherent-potential approximation. The site preference of alloying elements in gamma'-Ni3Al can be classified into four types: Co, Fe, Ru and Ir occupy Ni site or Cr, Mo, Re, Ti, V occupy Al anti-site (namely alloying elements occupy Al site while the removed Al occupy Ni site). Ti and V are the alloying elements which stabilize the gamma'-Ni3Al. The lattice misfit and the difference of elastic properties between gamma and gamma' phases are the causes of gamma' rafting, while the alloying elements will improve the differences. The effects of 1 at. % similar to 5 at. % alloying elements on lattice constant and misfit are studied, because of biggish atomic radius, Ir, Mo, Ti, Re and Ru increase the lattice constant of gamma/gamma' phase much faster, and the alloying elements have some impacts on the lattice misfit of gamma/gamma' phase. Re is the most remarkable alloying element which improves the elastic modulus of Ni-based superalloys.
