Reliable estimates of residual stresses based on non-destructive testing techniques have recently become an essential requirement for the efficient design of advanced materials. Over the last 10 years the neutron scattering technique has been recognized as a powerful tool in the characterization of such materials. In this paper we briefly describe the neutron diffraction facilities at the High Flux Reactor (HFR) at Petten. Experimental data on 2 specimens are presented. For the first specimen, an austenitic steel ring exhibiting sharp residual stress gradients, our findings are compared against similar data obtained elsewhere. For the second specimen, a metal/ceramic composite, the test data are compared against numerical results derived by numerical modelling of the composite's manufacturing process.
