Figure 3. Representative MDSC data.

Circles represent non-isothermal (scanning) data and correspond to the upper horizontal scale, temperature in °C). The open circles (○) are reversible heat flow data and the filled circles ([cirf ]) are non-reversible heat flow data. The non-isothermal heat flows show local minima at about 32.4 °C (down arrow), which are associated with dehiscence, and the dips in both data suggest a large endothermic event. Just before dehiscence, however, there is a small positive peak in the non-reversible heat flow data (starting at the up arrow), which is associated with an exothermic event. The filled diamonds (♦) represent the isothermal data and correspond to the lower horizontal scale, time in minutes. Again there is a small release of energy in the region indicated by the up and down arrows.
