Those engineering systems are assembled and then operated, inspected and maintained during performance in service environments. The environmental degradation of materials is well known phenomenologically. Mechanistic understanding is often the subject of intense research and concurrent debate. This is true of Environmentally Assisted Cracking, EAC. Debate is in part a reflection of the complexity of EAC. In order to develop an understanding of any EAC phenomenon researchers must take into account the microstructural characteristics of the materials, chemical interactions with the service environment and mechanical forces that are imposed as the system performs. This ongoing series of conferences has assembled researchers who have experience in all of these areas. Our goal is to develop a core of understanding in which appreciation of materials, chemistry and mechanics essentials are common to all EAC researchers. Looking to the future, the convergence of experimental tools which allow atom scale observations and simulation and modeling tools for characterizing materials as well as chemical and mechanical interactions provides room for optimism that mechanistic fundamentals will become elucidated and with such advances EAC will become better understood and better managed.
