The microstructural evolution of fatigue cracks in FCC metals
… The second set of experiments concerned the dislocation structure around crack tips. This set of experiments was performed on all the materials. The microstructure at arrested fatigue cracks on the free surface was compared to the microstructure found beneath striations on the fracture …

Impact of cellular dislocation structures produced by additive manufacturing on neutron irradiation damage evolution in stainless steel 316L
… revealed a network of sub-grain cellular dislocation structures decorated with oxide nano-inclusions and enrichment of heavy alloying elements at the cell boundaries. These features are thought to be responsible for AM SS-316L’s improved material performance in comparison to traditionally …

The influence of hydrogen on the evolving microstructure during fatigue crack growth in metastable and stable austenitic stainless steels
… attributed to enhanced plasticity and hydrogen-dislocation interactions stabilizing the austenitic matrix and confining slip to particular close-packed planes. The martensite acts as a fast diffusion pathway for hydrogen, leading to final fracture along martensitic laths or cleavage planes. In …
