Abstract
A technique for fast determination of residual stress profiles by neutron diffraction is described. The instrument is a variable wave length neutron spectrometer modified to incorporate a linear position sensitive detector and a fully automatic sample robot. The necessary measuring time for a typical strain profile is reduced by a factor of 3-10 compared to measurements performed on a standard triple axis spectrometer. The experimental set-up is described in the present paper and the performance is discussed. Finally the application of the technique is demonstrated by measurements of strain profiles around a fatigue crack in a CTS-specimen.
