FIG. 1.

DSC up scans of a calcium metaphosphate glass that was not subjected to mechanical stretching, but to thermal quenching at 2 K/min. Solid line: the heat capacity measured from the first up scan ; dashed line: the heat capacity from the second upscan . The DSC up and down scan rates were 20 K/min.

FIG. 2.

DSC up scan of a calcium metaphosphate glass stretched by a tensile stress of 0.2 MPa for 30 min at and then cooled at 2 K/min. Solid line: the heat capacity measured from the first up scan ; dashed line: the heat capacity from the second upscan . The DSC up and down scan rates were 20 K/min.

FIG. 3.

Excess heat capacity, , as a function of temperature, , for different tensile stresses (see lines a, b, c, d and e). Exotherms stand for the energy release from the stretched samples during up scans, while endotherms stand for the energy gain of the same samples during up scans. Inset: The total enthalpy, , released from the stretched samples during up scan as a function of the applied tensiles stress, . The error bars shown in the figure are determined using the standard deviation method.
