The concentration dependence of atomic short range order (SRO) has been studied in Ni 100-x Hf x and Re 100-x Ti x alloys (where x = 2, 5, 10, 15, 20 at.%) using the framework of transition metal model pseudopotential (TMMP). The ordering energies and Warren–Cowley SRO parameters were calculated for the Ni-Hf and Re-Ti alloys. It was found that this model predicted the correct sign of SRO for Ni 100-x Hf x system but failed in the case of Re 100-x Ti x alloys.

ABSTRACTMlultiatom interactions required in the statistical models used for the study of both the stability of ordered structures in the ground state and the chemical short range order, have been computed from the electronic structure for transition metal alloys. It is shown that : i) the most important interactions coming from “d” bands are those corresponding to self-retraced paths, the contributions of compact clusters being negligible ; ii) in general the results obtained using only second order pair interactions are valid provided that the concentration dependence of the pair interactions is taken into account. However in a few peculiar cases these results may be qualitatively modified.
