Modulated-temperature calorimetry measurements on the bulk glass-forming Pd[sub 40]Ni[sub 40]P[sub 20] alloy yielded the complex specific heat response of the deeply undercooled melt near the static glass transition. The imaginary contributions to the complex signal give direct access to the spectrum of slow α-relaxation modes of the undercooled liquid state that are frozen in upon vitrification. The results are discussed with respect to the kinetics of the glass transition and compared to results obtained from static equilibrium measurements. © 2001 American Institute of Physics.

    Plastic yielding in glassy solids has been interpreted as a strain-biased relaxation process, or, equivalently, as a strain-induced glass transition. The similarity between the structural relaxation induced by plastic deformation and thermal equilibrium of glasses has led to the formulation of...
