Electronic origin of solute effects on the mobility of screw dislocation in bcc molybdenum
Kangzhi Zhou, Jiajun Feng, Ziran Liu +3
In body-centered cubic (bcc) metals such as molybdenum, screw dislocations often exhibit non-Schmid behavior, moving in directions unpredicted by the Schmid law. The mobility of th…
