Plastic anisotropy and dislocation trajectory in BCC metals

Low-temperature plasticity in BCC metals is atypical, marked by an anisotropic elastic limit in violation of the Schmid law. Here, the authors show that these deviations can be quantified from subatomic deviations of the screw dislocation trajectory away from its average glide plane.
