Tensile specimens were machined from heat-treatedaustenitic stainless steel plate prior to and after 70 percentreduction by uni-directional rolling. In addition to a singlespecimen cut from the as-received plate, two specimens were cutfrom the rolled plate, with axes parallel and perpendicular to therolling direction, respectively. In situ measurements of the strainresponse of multiple hkl lattice planes to an applied uniaxialtensile load were made using neutron diffraction, to macroscopicplastic strains of around 1 percent. The experimental results arecompared with predictions from a self-consistent Hill-Hutchinsonmodel. The measured texture in the plate was approximately threetimes random; however, its effect on the hkl response was smallcompared to the residual strains left by rolling. The apparentelastic modulus of the planes is affected by the residual strains,which is attributed to the effect of micro-plasticity. Interpretationof residual stress measurements, for both single peak and Rietveldmeasurements is considered in light of these results.
