Research Field(Keyword & Summary)
  1. (1) X-ray stress and strain analyses for ultimately textured materials

    The first mission is development of new x-ray structural analysis methods for the materials consisting of infinite and infinitesimal texture limits. The former represents single crystals of Fe-Si and Fe-Ga, and the latter represents Zr-based and Fe-based metallic glasses. By using laboratory-based x-rays and synchrotron radiation x-rays, characteristic stress and strain features have been revealed.

  2. (2) Materials Characterization for advanced steels

    The second mission is studying the mechanisms of high performance for advanced steels. Textures, residual stresses and dislocation characteristics of TRIP, SMA and UFG steel are investigated by using x-rays and electron beams.
