Design using randomness: a new dimension for metallurgy [PDF]

open access: yesScripta Materialia, vol. 187, 2020, pp. 210-215, 2020
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 (dislocations, grain boundaries, vacancies, cracks, ...).
