How can we make the best use of image data showing the heterogeneity during reactions ?

April 10, 2018

Macroscopic phenomena, such as fracture, corrosion, and degradation of materials, are associated with various reactions which progress heterogeneously. Thus, material properties are generally determined not by their averaged characteristics but by specific features in heterogeneity (or ‘trigger sites’) of phases, chemical states, etc., where the key reactions that dictate macroscopic properties initiate and propagate.Here, we introduce a new persistent homology approach for identifying trigger sites and apply it to the heterogeneous reduction of iron ore sinters...

Exectives of SIP4MI projects, Drs. T. Kishi (Program Director), T. Yoshida, and N. Hosoda visited KEK. They met Drs. M. Yamauchi (Director General, KEK), M. Nomura (Exective Director), and K. Yamada (Director, IMSS), and confirmed the mutual cooperation. Then they visited XAFS-CT installed at NW2A, PF-AR, and attended a technical meeting on CFRP, where 18 researchers attending to the project discussed recent results and the future planning.


CFRP

We investigated the initiation and propagation of cracks in CFRP in term of multi-scale observations: in situ XAFS, STXM, XAFS-CT (to be installed in 2016 FY)

Ceramic
Coating

We investigated the initiation and propagation of cracks in ceramic coating in term of multi-scale observations: in situ XAFS, XAFS-CT (to be installed in 2016 FY)

XAFS-CT

Full-field XAFS-CT for microstructure & chemical state mapping will be installed at AR-NW2A in 2016FY

Materials Informatics

Materials Integration (MI) uses all scientific knowledge to help research and development of materials and structures.
