| Outline of Final Research Achievements |
Using both Small-angle X-ray (SAXS) and Neutron scattering (SANS), we confirm the formation of new phase with the diameter of 1nm and the change of their composition with increasing annealing temperatures in high nitrogen martensitic stainless steels . For this study, we have developed new compact SANS installed to the compact pulse neutron source in Hokkaido University. For evaluating the quality of the SANS profiles measured by in-house SANS, we comparing them to those measured by standard SANS which is installed in research reactor HANARO in Korea. The profiles measured by both SANS are perfectly same including absolute intensity level, indicating that the data obtained by in-house SANS are quantitatively correct. Above results of the formation of new phase is analyzed by the data obtained using in-house SANS. The in-house SANS can be powerful tools in the field of materials science.
