Chemically and mechanically driven creep due to generation and annihilation of vacancies with non-ideal sources and sinks

The classical concept of Nabarro creep is extended for a general dislocation microstructure. The specific mechanism of the creep consists in generation and annihilation of vacancies at dislocation jogs acting as non-ideal sources and sinks for vacancies. This mechanism causes the climb of dislocatio...
