Environment-assisted cracking has been and continues to be a critical failure mode for engineering structures. While complex, this damage mode reflects reality and requires cross-disciplinary expertise to understand mechanics, electrochemistry and hydrogen behavior and their interactions. This experimentally-based work focuses on traditional high-performance alloy systems (Al-, Ti-, Ni-, and Fe based alloys), additively manufactured components, and high entropy alloys in environments ranging from -100°C to 1000°C in electrochemically controlled aqueous conditions and high purity gaseous environments. High precision experimental data is coupled with multi-scale characterization techniques (from FIB/TEM to white light interferometry) to understand the salient roles of environment, mechanics and microstructure. CESE offers an unmatched team with capabilities in mechanics, localized corrosion and modeling, and hydrogen effects. The three faculty collaborate on several projects funded by the Department of Defense to understand both the controlling mechanisms for cracking in aluminum alloys as well as means for mitigating its impact through inhibitors and coatings. The Department of Energy funds research to develop and validate models for localized corrosion followed by Environment-Assisted Cracking to assist in safe spent nuclear fuel storage.
