x-ray diffraction in a containerless processing environment, is presented. Relatively sudden
changes were observed in the topological and chemical short-range order near 850° C, a
temperature that is 75° C below the liquidus temperature and 465° C above the glass
transition temperature. A peak in the specific heat was observed with supercooling, with an
onset near 850° C (the same temperature as the onset of ordering) and a maximum near …
