Numerical Analysis of Deformation Twin Behavior. Small Static Twin Lamellas

摘要: A detailed numerical analysis has been made of the energies and equilibrium configurations deformation twin lamellae under various conditions applied stress boundary energies. Exact expressions have used for self‐energies interaction associated with partial dislocations comprising using isotropic elasticity theory developed circular glide dislocation loops. It found that as and/or energy is increased, size stable lamella well number loops it decreases. Accompanying this decrease a correspondingly smaller activation. In respect critical step in formation activation first loop which requires stacking fault. Subsequent nucleation on adjacent planes, increases thickness, occurs spontaneously.
