Outline of Final Research Achievements |
To investigate interphase precipitation in steel, simultaneous analyses of small-angle neutron scattering (SANS) and Bragg-edge transmission were developed. SANS and Bragg-edge give the information about precipitation of carbide nanoparticles and ferrite matrix, respectively. In addition, simultaneous measurements of small-angle X-ray scattering (SAXS) and X-ray diffraction (XRD) using synchrotron radiation were performed. From the results of the in-situ measurements, the precipitation of the carbides and the transformation of the ferrite matrix were characterized.
