Interaction of reacting dislocations in superlattices of the CuAu and Pt2Mo type

A calculation is made of the strength of combinations of superlattices of a primary glide system consisting of two or three partial superdislocations and a single dislocation of the secondary glide system. Estimates are made of the contributions of dislocation combinations to the yield stress of alloys in which glide is effected by dislocations with different structures in different glide systems. The critical dislocation density at which plane sources are activated is determined.
