We have developed new stress measurement method which can determine the triaxial residual stress states by measuring the lattice strain in two orthogonal directions in the field of neutron diffraction. The triaxial stress analysis method for strain scanning method using high energy X-ray was almost the same method as the neutron diffraction technique. Therefore, this new stress measurement method in neutron diffraction was applied to the strain scanning method using high energy X-ray. As a result of applied stress measurement of SNC631 steel, the triaxial residual stress states were able to be obtained by measuring the lattice strain in only two orthogonal directions.
