Extended Data Table 2 Schmid factors of the different slip systems for a \(\left[\bar{{\rm{1}}}{\rm{05}}\right]\) tensile axis

From: Anomalous slip in body-centred cubic metals

  1. The resolved shear stress for a slip system with a Schmid factor f is τ = f σ, with σ the tensile stress applied along \(\left[\bar{1}05\right]\) axis. The slip systems, which are easier to activate, are the ones with the highest Schmid factors. The maximum Schmid factors are obtained for dislocations \({{\bf{b}}}_{3}\) and \({{\bf{b}}}_{4}\) gliding respectively in P23 and P14, thus defining the primary slip systems (in bold). In situ TEM tensile experiments (Figs. 1 and 2) show that the same \({{\bf{b}}}_{3}\) and \({{\bf{b}}}_{4}\) dislocations glide in P34, despite the lowest Schmid factor (indicated by a *) and that \({{\bf{b}}}_{1}\) and \({{\bf{b}}}_{2}\) dislocations glide in P12 (also indicated by a *).
