| Outline of Final Research Achievements |
To predict fracture and work hardening of metallic microstructure in structural materials, we have developed analytical methods for determining 2-dimensional distributions of dislocations and residual stresses by using X-ray diffraction methods. Firstly, the line-profile analysis based on the energy dispersive X-ray diffraction method was developed in 2012. High spatial-resolution line-profile analysis was developed in 2013 to characterize cold-drawn pearlitic steels. In 2014, These analytical methods were applied to the Co-Cr alloys with negative stacking fault energies.
