Popis: | The above-barrier glide of edge dislocations in binary alloys containing Guinier–Preston zones under high-energy impacts was theoretically analyzed. It was shown that the dependence of the yield stress of these alloys on the dislocation density in conditions of high-rate deformation deviates from the Taylor relationship and is a nonmonotonic function with a maximum. The maximum point corresponds to the dislocation density value at which their contribution to the formation of spectral gap becomes predominant. |
