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\rangle $ Burgers vector. Our numerical model incorporates non-Schmid effects. both the... https://www.jmannino.com/hot-choice-Lions-Big-Chain-Necklace-mega-pick/
