Abstract Scope |
Utilizing advanced characterization techniques to identify fundamental metallurgical processes that occur when materials are exposed to extreme conditions/environments is a requirement for nearly all students who work with Ian. Understanding the synergistic effects of corrosion and deformation processes at a fatigue crack tip on the bulk fatigue crack growth behavior of stainless steel alloys exposed to the high purity water environments typical of pressurized water nuclear power plants is the current focus of this former student. This presentation will focus on work utilizing a combination of special effects testing and advanced characterization techniques to identify whether a hydrogen-based mechanism is associated with corrosion fatigue crack growth in elevated temperature, high purity water. Integrating the knowledge gleaned from this work to the development of a multi-scale model of corrosion fatigue crack growth, which incorporates environmental effects, to predict fatigue crack growth rates will also be discussed. |
