The interatomic distances and nearest neighbor coordinations of constituent atoms in a series of metal-metal glasses: M'/sub 100-x/M''/sub x/ where M' = Zr, Nb, M'' = Fe, Ni, Cu and x varies from 30 to 60 at %, have been determined using the EXAFS technique in conjunction with the x-ray synchrotron source at Stanford. Fourier transforms of the EXAFS signals clearly indicate there are like as well as unlike atom pairs in the first coordination shell about both the M' and M'' atoms. The ratio of like and unlike pairs scales linearly with composition and is indicative of random mixing in these binary glasses. The M'-M'' separation are shorter than sum of the Goldschmidt radii and implies chemical interaction between the M' and M'' atoms.
