摘要：

A neutron-diffraction residual-stress measurement program has been in place for several years at the National Institute of Standards and Technology (NIST). Very recently a new, dedicated, state-of-the-art diffractometer has been installed at the NIST reactor. With it, the residual stress fields in a variety of engineering specimens have been determined. These include slices of railroad rails, weldments in steel plates and plastically bent steel pipes. Features of the new instrument and various experimental results will be discussed.
