Glass transition endotherms in the floppy, intermediate and stressed rigid phases of chalcogenide glasses are examined by modulated DSC. In general, the Tg endotherms consist of two parts; a reversing heat flow that represents the configurational energy difference between glassy- and liquid- state, and a non-reversing heat flow that represents relaxation enthalpy of a glass. Experiments reveal that the reversing heat flow in all the three phases does not age, reflecting the ergodic fraction of heat flow. On the other hand, the non-reversing heat flow steadily ages (at T < Tg) to saturate in both the floppy and stressed rigid phases. For glasses in intermediate phases, non-reversing heat flow term is found not only to nearly vanish, but a...
