NEW DIFFERENTIAL THERMAL-ANALYSIS METHOD

A new differential thermal analysis method has been developed which allows fast and accurate determinations of phase equilibria in condensed systems between 400 and 1100°. In this method the temperature is increased stepwise, heat effects being determined by analysis of the transient thermoelectric effects after each step. Between steps the temperature is kept constant until equilibrium is attained. The method has been tested in measurements of displacive solid-state transformations and melting points. © 1979 Wiley Heyden Ltd., Chichester and Akadémiai Kiadó, Budapest.
