Residual stresses in Inconel alloy 600, row 1, U-bend tubes, used in heat exchanges in nuclear reactors, were studied using an advanced x-ray diffraction instrument. Both axial and circumferential (hoop) stresses on the extrados, intrados, and flanks on the O.D. surface of several U-bends were mapped. The I.D. surface residual stresses at the extrados of the U-bend were mapped on one tube and subsurface stress measurements were made on the I.D. and O.D. surfaces of that tube. Service loads were simulated on one tube to ascertain combined effect of residual and applied stresses. Data from wall thickness and profilometry measurements were also correlated with residual stress measurements. 21 refs., 42 figs.
