Neutrons beamlines and research methods at neutron IR-8 research reactor

STRESS

Beamline created at the NRC "Kurchatov Institute" for internal stresses study. Designed to obtain direct information about deformations and stresses inside massive polycrystalline objects.

Neutron stress diffractometry method is used, that is based on measuring the displacement and broadening of diffraction peaks from microvolumes inside stressed material and comparing with unstressed samples.

The method allows to build detailed maps of the spatial distribution of internal stresses in the material. Test sample maximum weight is 100 kg.
