| Outline of Final Research Achievements |
Tensile testing device which could be attached to the scanning electron microscope was developed and the EBSD measurement system under loading was completed. In order to evaluate the damage by monotonic tensile loading, effective EBSD parameters and X-ray diffraction parameters can be determined. The elastic strains and stresses agreed well with the results calculated by the finite element method. In plastic region, KAM parameter measured by EBSD method is effective to evaluate the plastic strain. Full width at half maximum obtained by X-ray method could be expressed as a function of the value of KAM.
