In this work, we investigate the operation of Frank-Read (FR) sources in a refractory multi- principal element alloy (MPEA). Simulations of discrete dislocation motion in MPEAs is …
In this work, we calculate the local slip resistances (LSRs) in equal-molar MoNbTi multi- principal element alloy via molecular static simulations. We consider dislocations of either …
Voids of nanoscale dimensions in irradiated metals can act as obstacles to dislocation motion and cause strengthening. In this work, nanovoid strengthening and the influences of …

The generalized stacking fault energies (GSFE) and Peierls stresses are strongly related to the mechanical properties of refractory metals. In this work, the GSFE curves and Peierls …
Confined layer slip (CLS) is considered as the primary mechanism for plastic deformation in nanolaminates. It depicts the confined motion of a single dislocation between two parallel …
Abstract The Frank-Read (FR) source is a well-known intragranular dislocation source that plays an important role in size-dependent dislocation multiplication in metallic crystals. In …
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 …
The mechanical behavior of body-centered cubic (BCC) materials can be dramatically affected by the presence of interstitial solute atoms. We present a new phase-field …
In this work, we utilize atomistic simulations to calculate the generalized stacking fault energies (GSFEs), which are related to the dislocation glide process, on four types of slip …
