Chapter 4: Performing a Microstructure Simulation

For any of six Ansys predefined, validated materials (17-4PH, 316L, Al357, AlSi10Mg, Inconel 625, or Inconel 718), Microstructure simulations produce grain orientation and grain boundary results of the material for three 2D planes (XY, XZ, and YZ) simulating typical results of EBSD laboratory tests. Also, grain size distribution and orientation angle distribution are output in graph form using a circle equivalence method and orientation map for all three planes, respectively. Microstructure simulations are parametric so you can run several permutations to determine which process parameters will affect grain size the most. A Specific Random Seed input parameter may be used to instigate the same nucleation pattern for a given set of process conditions so that comparison simulations are possible.
