Abstract

In-situ measurements of small angle neutron scattering from a bulk metallic glass Ni15Pt60P25 were carried out in the momentum transfer range of 0.008 < Q < 0.08Å-1 as a function of the holding time during isothermal annealing at the temperature Ta = 483 K just below the glass transition temperature Tg = 488K. The small angle neutron scattering intensities initially increase with holding time and reach saturation values. The small angle neutron scattering intensity of the glass cooled down to room temperature after the annealing increases at the every momentum transfer value observed. The small angle neutron scattering intensities follow a Q-4 dependence and have no peak structure in the momentum transfer range observed. There is no evidence for any phase separations in nanometer length scale to occur in this glass.
