Influence of microstructural evolution and localized delta ferrite number on high-cycle fatigue crack opening and propagation rate

In this research, percentages of nickel as austenizer and chromium as ferritizer, in the molten metal pool of SS304L weldments are varied to analyze the effect on the produced delta ferrites morphology and volume. The resulting localized precipitation of delta ferrite and its effect on the fatigue c...
