Abstract Scope |
Stress induced sensitization in HAZ of 304 LN austenitic stainless steel was studied using Gleeble 3800. The test was performed at 650⁰ C at different stress level i.e. 0, 100 and 200 MPa. The response of sensitization was studied through the observation on change in microstructure, hardness measurement, TEM test, EBSD and electrochemical properties. Transmission electron microscopy confirmed the presence of Cr23C6 precipitation at the grain boundary for all the samples. EBSD result showed higher CSL boundary for sample without stress as compared to the sample with stress. Microstructure study, Hardness measurement and Electrochemical test indicated that chromium carbide nucleation was much in sample with induced stress. It was observed through this work that presence of stress enhances the sensitization. |
