Intergranular Stress Corrosion Crack Propagation in Sensitised Austenitic Stainless Steel (Microstructure Modelling and Experimental Observation)
Abstract
Three dimensional observations of intergranular stress corrosion crack nucleation and growth in sensitised austenitic stainless steel provide evidence for the development of crack bridging ligaments, caused by the resistance of non-sensitised special grain boundaries. A simple grain bridging model, introduced to quantify the effect of crack bridging on crack development, has been assessed via statically loaded room temperature tests, as well as high temperature/pressure water autoclave studies. Thermo-mechanical treatments have been used to modify the microstructure of type 304 austenitic stainless steel. Grain refinement has a significant beneficial effect on crack growth resistance. A beneficial effect of the residual stresses from surface machining is observed and compares well with the model prediction. Two and three-dimensional finite element models of intergranular crack propagation have been developed, which are consistent with the observed effects of microstructure. These models have the potential to be developed to describe the kinetics of short intergranular stress corrosion crack growth and coalescence.
