Residual Stress Measurements in Martensitic Stainless Steel
Residual stresses may be generated in target structural material used in accelerator-driven transmutation. Calibration curves were developed for transmutation target structural materials using positron annihilation spectroscopic (PAS) method. These calibration curves consisted of different line shape parameters (S, T & W) determined by the PAS method on martensitic stainless steel as a function of tensile stress/strain imparted to cylindrical specimens. This paper presents a comparative analysis of residual stresses in these specimens as a function of (S, T & W) determined by the PAS technique. The resultant data showed a consistent pattern in these parameters versus applied stresses ranging between the Yield and the Ultimate tensile strength.
