Thermodynamics is a science concerning the state of a system, whether it is stable,
metastable or unstable, when interacting with the surroundings. In this overview …

Abstract The Al-Co-W system and its binary sub-systems Al-Co, Al-W and Co-W were
critically reviewed. The thermodynamic description of the Al-Co-W system including all three …

Refractory high entropy alloys (RHEAs) emerge as promising candidate materials for
ultrahigh-temperature applications. Accurate phase stability is the prerequisite for design of …

A currently available commercial Calphad thermodynamic database was utilized to
investigate its applicability to alloy design in the new class of Co-Ni-based γ′-strengthened …

The development of multi-principal element alloys requires the navigation within a multi-
dimensional composition space, which has proven to be challenging. Various methods to …

An understanding of the thermodynamic and phase diagram data for the Al-Co-Fe system is
essential for Co-based superalloys as well as high entropy alloys. In this study a …

The thermodynamics of thermal vacancies in pure metals is analyzed within the compound
energy formalism. It is shown that depending on the choice of the compound energy of the …

As temperature increases, the thermal vacancy concentration in pure metals dramatically
increases and causes some strongly non-linear thermodynamic behaviors in pure metals …

In the present work, the Al–Co–Mn ternary system is thermodynamically modelled using the
Calphad approach. In the modelling, experimental data such as liquidus, solidus, tie lines …

The role of vacancies in thermodynamic models based on the compound energy formalism,
CEF, is studied by application to a binary phase with two sublattices where the two …
