In the framework of the CALPHAD approach to the thermodynamic modelling of solid solution phases inmulticomponent alloy systems, the Compound Energy Formalism has been successfully used for severalyears. However, for a few important phases with relatively complex crystal structure such assandmphases, many different descriptions have been used...

Metallic coatings can improve the high temperature resistance of superalloys serving in the gas turbines. In general they are Al–Co–Cr–Ni alloys with small Y additions to improve oxide scale adherence. In order to complete the construction of a thermodynamic database for coatings, thermodynamic assessments of four ternary systems have been...

A commercially available glass-ceramic composition is applied on a ferritic stainless steel (FSS) substrate reproducing a type of interface present in solid oxide fuel cells (SOFCs) stacks. Electrochemical impedance spectroscopy (EIS) is used to study the electrical response of the assembly in the temperature range of 380-780 °C and during...
