This paper reviews the recent research and development of high-entropy alloys (HEAs).
HEAs are loosely defined as solid solution alloys that contain more than five principal …

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 …

First-principles calculations based on density functional theory have been used to calculate
the temperature-dependent dilute tracer diffusion coefficients for 47 substitutional alloying …

The diffusivities of substitutional impurity elements in iron have been computed with ab inito
electronic density functional techniques, using exchange-correlation functional PW91 …

Diffusion regulates a vast number of materials properties and phenomena such as creep,
the focus of the present work. However, a deep understanding of the effect of how each …

Ferritic alloys strengthened with NiAl precipitates are being developed for elevated-
temperature applications. Due to the high concentration of Al in these alloys, they feature a …

The brittleness of FeCo alloy is generally caused by the B2 ordering behaviors. Alloying
elements V, Nb, Ta, Mo and W were experimentally found to be effective in improving the …

Coherent B2-ordered NiAl-type precipitates have been used to reinforce solid-solution body-
centered-cubic iron for high-temperature application in fossil-energy power plants. In this …

Aiming to design stable nanocrystalline (NC) materials, so far, it has been proposed to
construct nanostructure stability maps in terms of thermodynamic parameters, while kinetic …

Self and impurity diffusivities in Ni-based superalloys have been investigated by first-
principles calculations within five-frequency model. The vacancy formation energy, migration …
