Abstract This study investigates the heat capacities of intermetallic phases, specifically Ni 3 Fe, Ni 3 Mn, Ni 3 Ti, NiMn and TiAl, using differential scanning calorimetry (DSC), and enthalpy increments of Ni 3 Ti, NiMn and TiAl by means of drop calorimetry. The experimentally derived heat capacities of the respective phases are described using an Extended-Einstein model (EE-model). The experimental data, the fitted heat capacities, and literature data are in good agreement. The study also assesses the reliability of the heat capacities using enthalpy increments measured between 680 and 890 K. Experimental heat capacity data for ordered binary intermetallic phases are crucial thermophysical properties for constructing multicomponent thermodynamic databases which support computational materials design.

The study of structure generating processes is an interdisciplinary subject. Case studies from the various fields reveal similarities as well as differences in the methods of solution and also in the goals of analysis. The following selection serves to give an overview over the types of analysis typical for the various disciplines. It is by no means exhaustive. The individual articles are written by experts in the various fields with a strong emphasis on illustrating the points elaborated in the preceding chapter on the transdisciplinary foundations. Readers wishing to enhance their understanding and to proceed more thoroughly to the specific disciplinary details are put in the position to do so by consulting the cited literature.
