Microstructural Evidence Supporting the Existence of the SIPA Creep Mechanism

摘要

Stress-induced preferential absorption (SIPA) mechanism is a creep mechanism used to describe features of post-irradiation microstructure. Small variations in loop densities are thought to be a record of internal microstructures arising as a consequence of alloy texture and anisotropy of the SIPA mechanism. External stress can be discerned if external stresses exceed internal stresses. (ERA citation 04:003962)
