Relaxation and crystallization behavior of the metallic glass former PdNiP near the glass transition temperature — •Noah Colell — Universität Münster, Institut für Materialphysik, Wihelm-Klemm Str. 10, 48149 Münster

Analysis of Pd₄₀Ni₄₀P₂₀ metallic glass is conducted with Flash DSC measurements, realizing high heating and cooling rates. Relaxation is realized through systematically varying temperatures and durations of annealing by cycling to investigate the effects on glass transition and crystallization. Different relaxation modes (α and β) are targeted and their response to the heat treatment is analyzed. Due to the high rates available in Chip calorimetry, the range of temperatures available for relaxation experiments avoiding crystallization can be extended. As one results, it is observed that the relaxation enthalpy does not show a linear trend even with logarithmic scaling. This might be due to the combining effects of α and β relaxation. Through different annealing times different relaxation modes seem to be activated. The so-called shadow glass transition (β) can be seen with smaller duration and converges into a stronger enthalpy recovery with larger ones. This indicates a connection between the two relaxation modes.
