Microstructural investigation on the effect of cold work on environmentally assisted cracking of austenitic stainless steel
Abstract
Increased susceptibility to stress corrosion cracking (SCC) of stainless steels in good quality PWR primary coolant has been linked to prior deformation in the material. Deformation heterogeneity at the microstructural level is believed to induce susceptibility, however only limited research has been undertaken to quantify the link between microstructure and susceptibility. Analysis of electron backscattered diffraction data has been used to provide a unique description of the cold rolled micro structure of a grade of cold worked 304H stainless steel, which has been found to show high SCC propagation rates. The deformation twin lamellae within the bulk cold rolled material have been found to show preferential alignment with respect to the macroscopic direction of rolling. Additionally, deformation twins are found to interact with the crack significantly. The potential influences of this preferential microstructure alignment on the SCC behavior of the material are discussed.
