Since steel products have complex microstructures and chemical composition to achieve high strength and high functionality, it is important to characterize the internal structure with analytic techniques and to be able to predict their properties using simulation techniques. It is now possible to characterize and analyze the structural arrangements in raw steel materials and steel products, including the shapes of defects such as voids and cracks, as well as the crystallographic grain structure, by use of powerful new 3D characterization and analysis techniques, which can provide information on the internal structure on the micron or even submicron scale. It is expected, therefore, that application of new methods and results should lead to improvements in the mechanical properties of steel products. In this article, 3D analysis of the internal structure in a duplex stainless steel, and of strain propagation in pure nickel are presented as examples of the industrial application of 3D microstructural analysis.
