Stress relaxation in a nanoinclusion in response to extreme environments

摘要

We consider a stressed nanoinclusion in a crystalline matrix, which is initially coherent, but may relax through local plastic deformation under an impact of heat, mechanical load, irradiation, electric or magnetic fields. The reason for the relaxation process is an increase in the mechanical energy of the inclusion, when the environment conditions are drastically changed. A fingerprint of the proposed stress relaxation scenario is formation of a specific satellite dislocation loop in a close vicinity of the nanoinclusion.
