Correlation of microdistortions with misfit volumes in High Entropy Alloys

Nöhring, Wolfram Georg; Curtin, W. A.

2020 Condensed Matter

doi:10.1016/j.scriptamat.2019.04.012

Abstract: The yield strengths of High Entropy Alloys have recently been correlated with measured picometer-scale atomic distortions. Here, the root mean square microdistortion in a multicomponent alloy is shown to be nearly proportional to the misfit-volume parameter that enters into a predictive...

Design using randomness: a new dimension for metallurgy

Nöhring, Wolfram Georg; Curtin, W. A.

2020 Condensed Matter

doi:10.1016/j.scriptamat.2020.06.012

Abstract: High entropy alloys add a new dimension, atomic-scale randomness and the associated scale-dependent composition fluctuations, to the traditional metallurgical axes of time-temperature-composition-microstructure. Alloy performance is controlled by the energies and motion of defects...
