Engineering Fracture Mechanics | 1987

Abstract The crack growth characteristics, under constant load and in elevated temperature liquid sodium, were studied for Type 304 stainless steel through using linear elastic fracture mechanics. The crack growth rates are represented by the Arrhenius equation. Furthermore the crack growth rates in sodium, at 873 K and oxygen concentrations of 0.71 and 15 ppm, were examined. The crack growth rates seem to increase in accordance with increased oxygen concentration, however the difference is slight. Scanning electron microscope observations were made of corrosion products on the fracture surface at 15 ppm oxygen. However, at 0.71 ppm the corrosion products could not be observed. So the mechanism of crack growth seems to be related to impurities in sodium.
