Residual stress in joints by neutron diffraction at JRC
Two operating facilities are available for the purpose of residual stress measurements by neutron diffraction at the High Flux Reactor in Petten, The Netherlands. During the past two years considerable progress has been made on one of these (HB4) in upgrading the set-up of the instrument. The progress achieved by the implementation of various modifications in terms of statistical error and sampling time is shown through results of tests performed on standard specimens such as a stainless steel sample and an iron powder. Due to these improvements stress measurements are feasible in thick weld specimens and results are presented on such an austenitic steel piping weld specimen. Finally residual stress data for a ceramic/metal joint specimen based on neutron diffraction and numerical modelling are presented.
