High Resolution Residual Strain/Stress Measurements with a Three Axis Neutron Diffractometer
Original language description
New unconventional high-resolution neutron diffraction 3-axis set-up for strain/stress measurements of rather large polycrystalline samples is presented. Contrary to the conventional 3-axis set-up carried out by rocking the analyser and the neutron signal registered by a point detector, this new alternative uses a fixed rocking angle position of the bent perfect crystal (BPC) analyser and the detector signal is registered by an one dimensional position sensitive detector (1-d PSD). As this set-up exploits focusing in momentum space, a high-resolution determination of the lattice changes is achieved even on large irradiated gauge volumes. This alternative can be successfully exploited, namely in the strain/stress measurements on samples exposed to an external load, e.g. in tension/compression rig.
