| Research Abstract |
In this study, we developed a newly experimental method to measure the whole residual stress distribution from the surface to the interior of the carburized steel after quenching by complementary use of three kinds of radiation, x-ray, synchrotron x-ray and neutron beams. As a result, lattice plane spacing change in hardened case layer for stress evaluation could be determined successfully by measuring x-ray and neutron diffraction peaks. The residual stress distribution could be also evaluated by a combination of x-ray stress measurement for the carburized layer and neutron strain scanning for the interior.
