Dislocation cores, the regions in the immediate vicinity of dislocation lines, control a number
of properties such as dislocation mobility, cross-slip and short-range interactions with other …

This article reviews recent basic research on two classes of twins: growth twins and
deformation twins. We focus primarily on studies that aim to understand, via experiments …

An analytic model of the evolution of dislocation density in fcc polycrystals is described. The
evolution equations approximately account for most known dislocation storage, dynamic …

The stacking fault energy (SFE) plays an important role in the deformation mode selection
and consequently the mechanical properties of high entropy alloys. In the present work, the …

In alloys and high entropy alloys the stacking fault energy varies with the local composition.
The effects of these energy fluctuations on the strengthening are studied using dislocation …

In this work, we use density functional theory to calculate the entire generalized stacking
fault energy (GSFE) surface for eight transition metals with a face-centered cubic structure …

Dislocation-precipitate interaction and solute segregation play important roles in controlling
the mechanical behavior of Ni-based superalloys at high temperature. In particular, the …

In this paper, we discuss the formulation, recent developments and findings obtained from a
mesoscale mechanics technique called phase field dislocation dynamics (PFDD). We begin …

In this work, we present a phase field dislocation dynamics formulation designed to treat a
system comprised of two materials differing in moduli and lattice parameters that meet at a …

Using a density functional theory-phase field dislocation dynamics model, we reveal a
strong inverse relationship between the dislocation equilibrium core width and the …
