A theory of slip geometry in b.c.c. metals is given which is based on the assumption that the sessile‐glissile transformations of the splitting of screw dislocations are continually repeated during their motion. The sessile splitting is assumed to occur via the reaction 1/2 [111] = 1/6 [111] + 1/6 [111] + 1/6 [111] on a {110} and a {112} plane simultaneously as proposed by Foxall, Duesbery, and Hirsch [14]. The theory is developed analogically as in [8] where a different type of splitting was used. The previous results are compared with the present results for Fe‐3% Si and niobium.
