Abstract:
The distribution of dislocations and twins over the cross section of shock-loaded copper and 18Cr-10Ni-Ti steel specimens is investigated experimentally and numerically. It is found that the volume fraction of twins near the loaded surface and a spall crack is an order of magnitude higher than their fraction at the center of the target. The features of twins arising in different parts of the target are discussed. A model of a twinning mechanism in coarse-grained metals is proposed and used for numerical simulation of the dislocation and twin depth distribution in shock-loaded targets. It is shown that in thin targets (less than 1 mm thick), the distribution of twins can be even more uniform than the distribution of the dislocations density.
