Using the first-principles pseudopotential plane-wave method; the binding energies; density of states and lattice constants of a NiCrAlFe precision resistance alloy were calculated based on the disordered solid solution and L12-type ordered structures. The microstructure of the alloy was analyzed by high-resolution transmission electron microscope (HRTEM). Also; the electrical resistance of the alloy was measured after solid-solution and aging treatment. From the binding energy point of view; the L12-type ordered structure is more stable than the disordered solid solution structure. The calculation results of density of states and partial density of states show that in the L12-type ordered structure; Ni; Cr; Al and Fe atoms bond with each other more strongly than they do in the disordered solid solution structure. Thus the stability of the alloy is improved. In fact; L12-type ordered structure is revealed by HRTEM in the as-aged alloy; and its lattice parameters are close to the calculated results. According to the comparison of density of states at the Fermi level of different structures; the electrical conductivity of the alloy decreases due to the formation of L12-type ordered structure compared with that of the disordered solid solution structure; which is consistent with the experimental results. © 2020; Science Press.
