TL;DR: In this article, flux coupling phenomena such as solute drag by vacancies and radiation-induced segregation at defect sinks are systematically investigated for six bcc iron-based dilute binary alloys, containing Cr, Cu, Mn, Ni, P and Si impurities, respectively.

TL;DR: In this paper, the diffusion properties of a wide range of impurities (transition metals and Al, Si, and P) in ferritic alloys are investigated by means of a combined ab initio-atomic diffusion theory approach.

TL;DR: In this article, the authors investigated solute transport due to self-interstitial defects and radiation induced segregation tendencies in dilute ferritic alloys, by computing the transport coefficients of each system based on ab initio calculations of binding energies, migration rates, as well as formation and migration vibrational entropies.

TL;DR: The KineCluE code is introduced that implements the self-consistent mean-field theory for clusters of finite size, and features a set of useful tools, such as the sensitivity study routine that allows for the identification of the most important jump frequencies to get accurate transport coefficients with minimum computational cost.

TL;DR: In this article, the formation of nano-sized, coherent, solute-rich clusters (NSRC) is known to be an important factor causing the degradation of the macroscopic properties of steels under irradiation.
