Abstract Enthalpy relaxation in amorphous Pd_77.5 Cu_6.0 Si_16.5 in sub-T_g 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 (t_a). At lower temperatures, enthalpy relaxation exhibited two-stage in t_a dependence.
