Superdislocation dissociation and plastic deformation mechanism of ordered alloys with the L12 structure

摘要: where T F is the "friction" stress, ~ antiphase boundary energy in slip plane, s magnitude of shear zone associated with action source, fraction dislocations sliding maximum plane [5], obtained for stress at which dissociation superdislocations occurs effective planes a single dislocation. The distribution boundaries quite nonuniform [5]. Firstly, rate accumulation domains accomplished by edge orientation considerably higher than primarily screw slip. According to estimates case q = 2, 3, while 15.
