Symposium Hydrogen Effects on Materials Performance
Organizer(s) Samantha K. Lawrence, Los Alamos National Laboratory

Scope Numerous energy generation and transportation systems constructed of high-performance metal alloys are routinely exposed to hydrogen. The integrity of these systems is often challenged by a variety of hydrogen degradation modes affecting both structural components and storage media. The hydrogen-material interactions that ultimately lead to degradation occur across multiple length scales. Therefore, a particular goal of this symposium is to promote the exchange of ideas regarding multiscale experimental and theoretical methods for probing hydrogen-materials interactions.

The focus will be on integrating experimental and computational approaches to understanding hydrogen-assisted damage in a wide variety of complex materials systems, such as advanced steels, energy-related materials, and aerospace materials.

The subject areas of the symposium include, but are not limited to:
-Hydride formation as a degradation mode
-Metal hydride utilization
-Industrial issues involving hydrogen-assisted degradation
-Hydrogen effects on fatigue and fracture
-Advanced experimental methods for studying interfacial effects on hydrogen transport
-Applications of novel in-situ micro- and nanomechanical characterization techniques for studying hydrogen-microstructure interactions
-Simulation of hydrogen interactions with metal surfaces and hydrogen degradation mechanisms
-Development of multi-scale models describing hydrogen-material interactions
