CHEMICAL SHORT-RANGE STRUCTURE OF (TI0.76NI0.24)(100-X)V-X AMORPHOUS-ALLOYS

The chemical short-range order in a ternary amorphous alloy system can be extracted from the neutron diffraction data, provided that the ave rage neutron scattering amplitude [b] can be reduced to zero. In the p resent experiment, the (Ti0.76Ni0.24)(100-x)V-x ternary system is desi gned by taking an advantage of the fact that the values of [b] for Ti0 .76Ni0.24 and V are almost zero. amorphous single phase samples were o btained over the range 0 less than or equal to x less than or equal to 40 by mechanical alloying. The Warren chemical short-range order para meter can be deduced from the radial concentration function. From a co mparison of it with a perfectly chemical short-range order parameter g iven by - C-Ni/C-Ti,C-V we revealed further that an increase in V conc entration in the amorphous matrix Ti0.76Ni0.24 promotes the chemical s hort-range order between Ni and X = Ti or V atoms.
