Abstract
En 中文
This study investigates the heat capacities of intermetallic phases, specifically Ni3Fe, Ni3Mn, Ni3Ti, NiMn and TiAl, using differential scanning calorimetry (DSC), and enthalpy increments of Ni3Ti, 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.
