Meeting 2017 TMS Annual Meeting & Exhibition
Symposium Energy Materials 2017: Materials for Oil and Gas and AMREE Oil & Gas III
Presentation Title A Combined Micromechanics/Materials Science Approach to Understanding High Temperature Hydrogen Attack
Author(s) Mohsen Dadfarnia, May L Martin, Petros Sofronis, David E Moore, Steve E Orwig
On-Site Speaker (Planned) Mohsen Dadfarnia
Abstract Scope High Temperature Hydrogen Attack (HTHA) of steels plagues higher temperature applications, especially in the petrochemical industry. Focused-ion beam machining allows extraction of samples from site specific locations for subsequent examination in the transmission electron microscope. By using this technique to explore the microstructure immediately ahead of crack tips and along cavitated grain boundaries, a better understanding of the physical processes of the HTHA process can be gained, which can guide the development of models for the degradation process accounting for methane formation and creep cavitation. Based on the underlying deformation and fracture mechanisms, we propose a model for grain boundary failure due to HTHA. The model addresses growth of the pressurized voids on grain boundaries while considering the interaction of the void growth with creep of the surrounding grains under constrained conditions. Effort is made for the model to be simple to use while capturing the underlying chemomechanics.
