Character of the stressed state of fcc metal single crystal and the resistance to dislocation glide from secondary systems attracted by dislocations

Stresses in secondary glide systems are taken into account in calculations of the strength of dislocation combinations in an fcc crystal with deformation axis oriented in [010], [¯111], and [¯10¯1] directions. The coefficientα characterizing the contribution of the reacting component of the dislocation forest to the yield stress is studied as a function of the dislocation densityp.
