First-principles Calculation on Screw Dislocation Core Properties in BCC Molybdenum
Predicting atomistic properties of a dislocation is a first step toward an understanding of plastic behavior of materials, in particular BCC metals. The core structure and Peierls stress of a screw dislocation in BCC metals have been studied over the years using the first-principles and empirical methods, however, their conclusions vary due to the inefficiency of the methods. We have executed f...
متن کاملFirst-principles Calculation on Core Structures and Peierls Stress of a Screw Dislocation in BCC Iron
Predicting atomistic properties of a dislocation is a first step toward an understanding of plastic behavior of materials, in particular BCC metals. The core structure and Peierls stress of a screw dislocation in BCC iron have been determined using the first-principles calculations based on the density functional theory with the large-scale supercell containing 231 atoms. For the a0/2[111] scre...
متن کاملSingular orientations and faceted motion of dislocations in body-centered cubic crystals.
Dislocation mobility is a fundamental material property that controls strength and ductility of crystals. An important measure of dislocation mobility is its Peierls stress, i.e., the minimal stress required to move a dislocation at zero temperature. Here we report that, in the body-centered cubic metal tantalum, the Peierls stress as a function of dislocation orientation exhibits fine structur...
متن کاملCalculating the Peierls energy and Peierls stress from atomistic simulations of screw dislocation dynamics: application to bcc tantalum
We introduce a novel approach to calculating the Peierls energy barrier (and Peierls stress) based on the analysis of the dislocation migration dynamics, which we apply to 1/2a〈111〉 screw dislocations in bcc Ta. To study the migration of screw dislocations we use molecular dynamics with a first principles based embedded-atom method force field for Ta. We first distinguish the atoms belonging to...
متن کاملComment on ‘‘Lattice Resistance to Dislocation Motion
In a recent Letter [1], Dutta et al. showed that dislocations move faster in thin films than in the bulk and that this is caused by a reduction in lattice resistance at the nanoscale. In this Comment, I show that the results presented in [1] do not agree with previously published results and are not reproducible. Furthermore, I am able to show their explanation of lattice resistance is not supp...
