Is the Compensation Effect a Phase Transition?
The compensation effect, i.e. the linear dependence between characteristic enthalpy and entropy, has been frequently described in many fields of science and its close relationship to a phase transition is often assumed. In this paper it is shown for example of grain boundary segregation that the compensation effect principally differs from the phase transition although they can occasionally occur at the same temperature.
