Measuring Residual Stresses in Vamas International Calibration Block with the Stress Diffractometer of Ir-8 Reactor

Аннотация

The results of measuring residual strains/stresses in the VAMAS international calibration block with the STRESS neutron diffractometer installed in the horizontal channel of the IR-8 reactor at Kurchatov Institute are presented. The measurement results are in good agreement with calculated stress values. The measurements have shown that the STRESS diffractometer is comparable in terms of its capabilities for measuring stresses with state-of-the-art diffractometers installed on higher power reactors.
