Intergranular Stress effects on Stress Corrosion Cracking Susceptibility of Stainless Steels

DOI

The stress corrosion cracking (SCC) of austenitic stainless steels (ASS) has been shown to increase with cold work (CW). However, the mechanism by which CW and the subsequent strain path affect the susceptibility to SCC is yet to be fully understood. Crystal Plasticity Finite Element Model has been developed to assess the influence of CW and subsequent strain path along the 3 principal directions on the stress and strain evolution at microscale level. Whilst stress increases with CW, higher intergranular stresses were also predicted along rolling and transverse direction upon re-loading.The objective of this experiment is to measure the evolution of internal elastic strains in cold worked ASS along different strain paths using ENGIN-X. Stresses will be determined from Hooke's law and the experimental data obtained will be used to validate the model predictions.
