EVALUATION OF RESIDUAL-STRESSES IN STAINLESS-STEEL CLADDINGS

The residual-stress in-depth profiles have been evaluated in AISI 308L and 309L stainless-steel claddings using three different techniques: the X-ray diffraction, the neutron diffraction and the step-by-step ho le-drilling method. These claddings are strongly textured and contain up to 10-percent ferritic phase. For this reason, the elastic characte ristics of the material have been calculated from the single crystal c ompliances through a self consistent micromechanical approach, The res ults obtained with the three different experimental techniques are com pared and discussed, The effect of a stress-relief heat treatment is a lso studied.
