The Role of the Environment in Accelerating Material Failure: Real World Examples and How Research Addresses the Challenges

  This is the fourth and last Horizons Speaker Presentation for the 2021 season. We will hear from Dr. Jen Locke of Ohio State University, Department of Materials Science and Engineering in the College of Engineering. Her research aims to understand the processes that lead to failures promoted by the environment so that one can properly design against it or mitigate the problem. Many engineered structures (cars, aircraft, bridges, ships, nuclear waste storage containers, etc.) are susceptible to degradation from the environment in which they are utilized or made through both corrosion and environment assisted cracking (EAC, both stress corrosion cracking and corrosion fatigue). Corrosion occurs by electrochemical (i.e. redox reactions meaning involving electron exchange between species) surface reactions that actively removes metal from a surface. Dr. Locke’s presentation will discuss the important role metal/environment interactions play in engineered structure performance by presenting real world material failures that have occurred because of the interactions of corrosion and stress. Active research in Locke’s lab will also be presented to highlight how on-going academic research can be used to improve understanding of and prevent corrosion and EAC related failure.   Join Zoom Meeting https://us02web.zoom.us/j/86013551543?pwd=dnFmNys0SkpsVkIxM05jT012Smh2QT09 Passcode: horizons21 The Speaker: Jenifer (Warner) Locke is an assistant professor in the Department of Materials Science and Engineering and the Fontana Corrosion Center at The Ohio State University. Jenifer’s primary research interests are in environment assisted cracking (EAC) and corrosion of metals and alloys, which is the study of how the environment degrades metal performance and properties to reduce the sustainable and reliable use of a structure. Locke’s lab is funded through programs with ONR, NSF, DoD, and the DoE, as well as ongoing industry collaborations with DNV-GL, Arconic, Ford, Honda, PNNL, Battelle, and PPG.
