Abstract

This paper develops a robust CAD-based methodology for simulating 3D microstructures of polycrystalline metals using crystallographic input data on sections created by a focused ion beam (FIB)-scanning electron microscopy (SEM) system. The method is able to construct consistent polycrystalline microstructures with control on the resolution necessary for meaningful computational analysis in microstructure-property estimation. The microstructure simulation methodology is based on a hierarchical geometrical representation using primitives used in CAD modeling. It involves steps of data cleanup, interface point identification, polynomial and NURB…(more)
