Abstract ： Enthalpy relaxation in amorphous Pd77.5 Cu6.0 Si16.5 in sub-Tg temperature region was studied by differential scanning calorimetry (DSC). Enthalpy change due to annealing, which was measured by deducting the effect of glass transition, increased gradually to a saturated value with increasing annealing time (ta ). At lower temperatures, enthalpy relaxation exhibited two-stage in ta dependence.
