Nondestructive stress measurement technique by neutron diffraction

Suzuki, Hiroshi  

The neutron diffraction method is known to be a nondestructive method which can measure the residual strain and stress in material with a few centimeter order depth. Furthermore, the microstructural factors, such as microstrain, texture and dislocation density, can be evaluated by analyzing the diffraction profile measured by neutron diffraction. In the presentation, I will introduce the neutron stress measurement technique as well as some applications.
