Two- and three-dimensional microstructural characterization of a super-austenitic stainless steel

Controlled Poisson Voronoi tessellation for virtual grain structure generation: a statistical evaluation

“…Polycrystalline FE has given valuable insights into grain-to-grain interaction behaviour and local deformation mechanisms, acts as an effective utility to simulate micro-forming processes for small scale metal products, and is capable of simulating local damage processes of components in service [2,3]. Since stress and strain are related to grain size, shape, orientation and their distributions, FE micromechanics simulations require a grain structure modelled within a FE/CAE Representation of a grain structure can be obtained directly by mapping metallographic observations to a FE model, by processing digitised images [4][5][6][7] or SEM/EBSD data to reconstruct the grain structure [8][9][10][11]. However, these approaches are generally very time-consuming and laborious for practical applications.…”

Morphology and Crystallography of Sub-Blocks in Ultra-Low Carbon Lath Martensite Steel

“…Recently, three-dimensional (3D) tomography has been developed for metals, which enables characterization of the 3D morphology of complicated microstructures. 6,7) Thus, 3D visualization is expected to provide new understanding of the characteristics of the sub-blocks.…”

Development of a Novel Approach for Fatigue Life Prediction of Structural Materials

“…Since the original development of AL6-XN steel was targeted towards the off-shore platform applications, the corrosion resistance to the salt water environments [30][31][32] was a concern. Other work on the properties of the stainless steel has been done primarily in the microstructural features [29,33] and [34] and crack propagation in the welds [35,36]. Modeling of the plastic behavior was conducted based in particular on crystal plasticity theories [37][38][39].…”

“…New and advanced technique for three-dimensional analysis of the microstructure was developed and applied to the AL6-XN steel by Lewis and co-workers [33]. The technique is a combination of a serial sectioning and electron backscatter diffraction (EBSD) which allows for a reconstruction of individual grains with boundary conditions in three dimensions.…”
