Materials for Energy, Sustainablility and Extreme Conditions
BSynergies and challenges for materials in extreme environments
Materials in a flux of high-energy particles, from nuclear to space applications, exhibit enhanced susceptibility to deformation, corrosion, loss or change of desired thermal, mechanical or electrical properties. Experiments and simulations to understand the synergy between different features of these extreme environments are the focus of this symposium.
Scope:
One of the great engineering challenges of today is the durability of materials operating in extreme environments. From new materials for fusion energy and fission reactor materials, - both key for sustainable energy production - to materials for long missions in outer space. Materials in such environments can be pushed far from equilibrium and can be exposed to synergies that act to their detriment.
Often, barriers exist between experiments and simulations, or between research in metals, ceramics and polymers, or between structural and functional materials. This symposium aims at breaking these barriers, thereby enabling information transfer across different aspects of similar phenomena occurring in materials brought far from equilibrium.
We encourage submissions in the fields of, but not restricted to, 1) sensor or superconducting materials in space or nuclear applications, 2) structural materials under joint application of stress and irradiation, 3) materials in simultaneously corrosive and irradiative environments, 4) evolution of complex microstructures under irradiation, such as grain boundaries in nanocrystalline metals, interfaces with precipitates or dislocation structure, 6) light element in extreme environments, a relevant example of which is deuterium in fusion materials. Relevant materials include Nb-based superconductors, Si and SiC sensors or SiC-based composites, tungsten and steel, Zr-alloys.
In all cases, both experimental and theoretical contributions are welcome, especially when one or more environmental aspects are acting alongside irradiation. Since data is often scarce in this field, we also welcome discussions on how to apply novel methods to address this lack of data. These methods can utilise high-throughput innovative experimental techniques and experiment designs, applications of machine learning, or similar.
Hot topics to be covered by the symposium:
- Challenges for and evolution of diagnostics materials in harsh applications: experiments and simulations
- Innovative data analysis to tackle the scarcity of experimental data in extreme environment
- Innovative methods: high performance computing for numerical simulation and high throughput experiments
- Synergies in alloys for nuclear applications under aggressive environment: mechanical loading or corrosion under irradiation
- Environment and contamination effects
- Superconductors and sensors: REBCO, Nb-based superconductors, Si and SiC
- Nanocrystalline materials, nano-precipitates or otherwise complex microstructure evolution under irradiation
