Wang Lab
Machine-translated · View original
A lab that observes at the nanoscale how materials break down in order to uncover the process of failure.
AboutAbout the lab
Making the process of material failure visible
The Wang Lab studies the mechanisms by which mechanical materials degrade over long periods of time.
Toward a decarbonized society, the lab uses cutting-edge nanoscale analysis techniques to investigate, at multiple scales, the structure of materials placed in harsh environments.
Using in situ observation and testing methods, the lab elucidates the process by which materials fail from a mechanistic perspective and visualizes it.
By combining experiments and computation, the lab aims to contribute to the development of next-generation structural materials.
Key terms
- In situ observation
- A way of observing a material in place, watching how it changes while force or heat is applied to it
- Hydrogen embrittlement
- A phenomenon in which hydrogen that has entered a metal makes the material brittle and prone to breaking
- First-principles calculation
- A method that calculates matter from the level of atoms and electrons to predict its properties without relying on experiments
ResearchResearch themes
To gain a deep understanding of the aging degradation of mechanical materials in a decarbonized society, the lab uses cutting-edge nanoscale analysis techniques. It explores structural properties under harsh environments such as high temperatures, across multiple scales.
*Illustrative imageInteraction between hydrogen and materials
Toward a hydrogen energy society, the lab develops in situ measurement techniques that can be used in harsh environments such as high temperature and high pressure. It systematically clarifies the mechanical and chemical behavior of hydrogen and structural materials.
*Illustrative imageFirst-principles calculations of corrosion-resistant alloys
Using first-principles calculations, the lab evaluates the oxidation resistance and resistance to hydrogen embrittlement of new alloy compositions. Using Tohoku University's supercomputer, it investigates at the microscopic scale how alloying elements affect material properties.
