Figure 2
Sketch of a G–T diagram which is in accordance with the observed phase transformations. The implied phase transformations, the transformation temperatures and the enthalpies of transformation derived from DSC measurements are given below the ordinate. The diagram is based on information and similar diagrams in previous work (Castro et al., 2010; Cherukuvada et al., 2010). The (*) implies that the transition enthalpy of the β to γ transition is not well determined, because the β sample was contaminated by γ-form crystals. |
