Abstract Scope |
Relentless process improvements in the steel industry have rendered non-metallic inclusions, once common and conspicuous impurities, now the needle in the haystack. The role of smaller and fewer inclusions in ever cleaner steel remains acute in increasingly demanding applications, but characterizing them is increasingly challenging. Locating, imaging, analyzing and understanding nanoinclusions requires a connected approach whereby multimodal submicron and nanometer-scale data is combined, from light, electron, x-ray and ion beam microscopy. We will present advances in sub-nanometer inclusion and feature analysis, femtosecond laser ablation to access deeply-buried features, and how integrated in situ heating, tensile and spectroscopic and crystallographic experiments reveal previously inaccessible structural and elemental detail on inclusions. We also describe a previously unknown effect whereby certain inclusions are only visible at specific beam conditions.
