Short-range order in dilute solid substitutional solutions Ni−Nb and Ni−Ta

The type of short-range order in dilute alloys Ni-Nb and Ni-Ta is predicted using a model potential. A new experimental method is proposed to investigate short-range order in dilute alloys and, with its help, the existence of non-primitive short-range order is demonstrated in Ni-Nb and Ni-Ta solid solutions with a small amount of the second component, supporting the thoery
