Scope Environmentally assisted cracking (EAC) is material degradation that occurs because of the deleterious interaction of mechanical stresses and an external corrosive environment, which often uniquely localizes within an occluded crack. EAC, including both stress corrosion cracking (SCC) and corrosion fatigue (CF), may significantly limit the functional life of many structures/components and cause unexpected failure in many fields, such as the oil and natural gas industry, advanced nuclear power plants, aerospace, and navy applications. EAC can occur in metals, alloys, ceramics, composites, and may be a potential problem in recently developed materials such as additively manufactured materials, high entropy alloys (multi-principal element alloys), etc.
This symposium provides a forum for discussion of research and advances in experimental approaches, material behavior, simulations, and lifetime assessment modeling related to EAC, both SCC and CF. This symposium seeks technical presentations related to experimental and modeling studies of various types of EAC, such as hydrogen embrittlement, stress corrosion cracking, corrosion fatigue, and liquid metal embrittlement.
The symposium will encompass, but is not limited to, the following themes:
• Advances in test methods and instrumentation for experimental approaches to assess EAC performance in laboratory, simulated service, and service environments;

• EAC in additively manufactured materials, compositionally complex alloys and high-entropy alloys;

• Advances in service monitoring and non-destructive evaluation/testing capabilities;

• Development of physics-based approaches for EAC monitoring and prognostics;

• Multiscale models to understand EAC mechanisms and predict the lifetime of structural materials in harsh environments;

• Development of databases for material EAC behavior in laboratory or service environments;

• SCC and CF of alloys in high-temperature water, seawater, molten salt, or other environments;

• Fracture and fatigue of alloys in hydrogen producing environments;

• Degradati
