Notes:
In this study we present a direct comparison between residual strain measurementscarried out on the same inertia friction weld using ENGIN-X at ISIS, UK and the new strainscanner SALSA at ILL, France. ENGIN-X is a time of flight (TOF) instrument, which receivesneutrons from a neutron spallation source, while the SALSA Strain-Imager, a high resolutiondiffractometer, is based at a research reactor source with a continuous neutron flux and is operatedwith a constant wavelength. The purpose of this study was to demonstrate a confidence in crosscomparingfuture strain measurements to be performed at ENGIN-X and SALSA. Measurementswere carried out on medium size inertia friction welded nickel superalloy test-piece, which show nosignificant crystallographic texture across the weld line. The results demonstrate that, even thoughresidual stresses determined on SALSA only rely on a single peak analysis (in this case the (111)reflection), the results show excellent agreement with the measurements carried out on ENGIN-X,where strain is determined from multi-peak Rietveld analysis
