Residual stress determination by means of neutron diffraction

摘要

Neutron diffraction is becoming an increasingly important tool for the determination of triaxial residual stress distributions for planning programs in this area. Examples of the application of the technique to subsurface residual stress determination in metals and composites will be presented, along with some near-surface results. The significant textures of features of new neutron instruments for residual stress study will be summarized.
