Differential dislocations in martensite-type interphase boundaries
- 24 Downloads
The tensor describing the density of differential dislocations, formed on interphase surfaces with a martensite transformation and on boundaries of mechanical twins, is calculated. Differential dislocations arise due to the transformation of Burgers vectors and dislocation lines in the process of their succession from the parent crystal. The dependence of the density of differential dislocations on the starting dislocation structure, transformation geometry, and the transformation matrix of the lattice with the transformation is demonstrated.
