Screw dislocations in BCC transition metals: from ab initio modeling to yield criterion
We show here how density functional theory calculations can be used to predict the temperature- and orientation-dependence of the yield stress of body-centered cubic (BCC) metals in the thermally-activated regime where plasticity is governed by the glide of screw dislocations with a $1/2 \langle 111...
