• The structures of the amorphous alloys with atomic percent compositions Ni_<68.21>Cr_<14.22>P_<17.22>C_<0.35> (MBF 65) and Ni_<67.33>Cr_<14.31>B_<18.11>C_<0.25> (MBF 80), which have similar Ni-Cr-C components, have been studied and compared by X-ray diffraction. The interference functions, atomic distribution functions, and radial distribution functions were calculated from the X-ray diffraction intensity data. The nearest-neighbor distances and coordination numbers were determined to be 2.52±0.01 Å, 12.50±0.10 for MBF 65, and 2.48±0.01 Å, 12.75±0.11 for MBF 80, respectively. The observed nearest-neighbor distance is in good agreement with a simple contact-distance packing model using the calculated atomic radii and a coordination number of twelve. These results are compared with the same composition of Ni in amorphous Ni-P and Ni-B alloys.
