Unlike FCC metals, where slip occurs on well-defined {111}⟨110⟩ systems and the dislocation physics is relatively well understood, BCC plasticity is governed by thermally activated screw dislocation motion with non-planar core structures. This produces strong temperature and strain-rate sensitivity, and a persistent debate about which slip planes are actually active under different loading conditions.</p>
