Non-Destructive Analysis of Surface Integrity on Parts from Austenitic Steel for Nuclear Industry

Abstract

This article is focused on non-destructive detection method of residual stress and chemical properties of stainless steel. By X-ray diffractometry, there it is possible to determine accurately the values of residual stress and austenite percentage without any damage the sample without any change of its original function. Identification of residual stress and its distribution can improve the prediction of failures or damage incidences due to workload over lifetime of components. It can be also used as one of evaluation parameter of suitability of applied manufacturing technological operations.
