Abstract
In this study, semi-nondestructive measurement of non-equibiaxial stress using the indentation technique without a reference load under the non-stress state has been applied to low-carbon austenitic stainless steel welds. In order to clarify the material dependency of the applied procedure, two constants (the load ratio and the conversion factor) for stress determination were experimentally quantified and compared with those of high-strength structural steel. The accuracy of stress measurement by the procedure applied to low-carbon austenitic stainless steel welds was verified through a comparison with the X-ray diffraction and stress relief methods. Based on the results, the applied procedure had less dependency on the material properties of these steels and was in good agreement with the conventional techniques in the overall distribution of residual stress.
