Nondestructive Measurement of Residual Stress by Neutron Diffraction and the R&D of the Diffractmeter

The nondestructive measurement of residual stress by neutron diffraction methods was briefly described. The first neutron diffractometer dedicated to three dimensional nondestructive relatively deep residual stress measurement and analysis at CARR in China was researched and developed. This shall provide research and experiment platform for the domestic materials science and engineering customers.
