Abstract: A neutron diffraction load frame has been constructed for the Second Generation Neutron Residual Stress Mapping Facility (NRSF2) at the High Flux Isotope Reactor, Oak Ridge National Laboratory. The load frame is designed to study micromechanical behaviour of materials under applied tensile or compressive loads and to characterize specimens with stress risers (e.g., cracks) while under load, in combination with the existing mapping capabilities at NRSF2.
