Kauzmann temperature of alloys obtained by different methods

Based on calorimetric measurements, the Kauzmann temperatures of alloys are determined by the isentropic condition, the Vogel-Fulcher law and the melting points of the components of the alloy. The Kauzmann temperatures obtained by these methods are identical within our error. The effects of the heating rate, the specimen mass and the pan type on the temperature of the calorimeter are measured. A linear dependence of the glass transition temperature on the logarithm of the heating rate for organic and metallic glasses is confirmed within the experimental range. Some methods are utilized to extend the measuring temperature range of the specific heat for undercooled liquids and for the crystals near their melting points.
