Metals with the hcp crystal structure have a wide variety of mechanical and physical
properties, and understanding the links between atomic processes, microstructure, and …

We investigate the structure and mobility of single self-interstitial atom and vacancy defects
in body-centered-cubic transition metals forming groups 5B (vanadium, niobium, and …

Dislocations are ubiquitous linear defects and are responsible for many of the properties of
crystalline materials. Studies on the glide process of dislocations in bulk materials have …

This paper is the first of three that overview the main mechanisms that drive the
microstructure evolution in Fe alloys under irradiation. It focuses on pure α-Fe and compiles …

Molecular dynamics computer simulation was applied for an extensive study of primary
damage creation in displacement cascades in copper and α-iron. Primary knock-on atom …

We study self-interstitial cluster migration properties, such as dimensionality of the motion
and activation energy barrier, as functions of the cluster size, by means of molecular …

We report the results of molecular dynamics simulations of self-interstitial cluster diffusion in
pure α-Fe and in a dilute Fe–1.0 at.% Cu alloy for a number of cluster sizes, n<~ 20. We find …

The dynamic behavior of nanoscale prismatic dislocation loops can significantly affect the
microstructural variation in crystalline materials upon processes such as plastic deformation …

The design of radiation-tolerant polycrystalline materials has been mainly based on the
control and manipulation of grain boundaries (GBs) that leads to annihilation of point defects …

Thermally activated Brownian motion of interstitial defects is one of the factors driving the
evolution of microstructure of crystalline metals under irradiation. In the limit of relatively …
