Fast neutron surface strain scanning with high spatial resolution

Popis výsledku v původním jazyce

A method for near-surface strain scanning measurements using neutron diffraction with large gauge volumes is described. The approach corrects for pseudo (spurious) strains related to partially illuminated gauge volumes and enables deconvolution of the large gauge volume measurements into the assumed real profile. It was validated against X-ray and neutron diffraction experiments with very high spatial resolution. The analysis of the results shows that neutron diffraction based strain measurements with standard (or large) sized gauge volumes are possible to reproduce the real strain profile free of artificial effects related to partial illumination. Compared to measurements with smaller gauge volumes gains in counting time of up to a factor of fifteen can be achieved without appreciable loss in spatial resolution.
