Protodefect as a Basis of Multilevel Nanoscale Plasticity of Crystal Materials

Atomic mechanisms of plastic deformation initiation in materials with crystal structure are investigated. It is shown that thermal fluctuations can be a reason for structural defect generation and there is a threshold strain value at which zones with local structural changes (protodefects) grow almo...

description Atomic mechanisms of plastic deformation initiation in materials with crystal structure are investigated. It is shown that thermal fluctuations can be a reason for structural defect generation and there is a threshold strain value at which zones with local structural changes (protodefects) grow almost abruptly. The calculations illustrate that protodefect formation is induced by a local expansion of atomic volume.
