Grain-Scale Crystal Plasticity Finite Element (FE) Simulations of Waspaloy during Hot Deformation

摘要

This report results from a contract tasking Max-Planck-Institute for Eisenforschung as follows: The project aims to understand and predict the mechanical, crystallographic, and topological behavior of gamma grains in Waspaloy during plastic deformation at high temperature. The study will be conducted by use of a crystal plasticity finite element method that updates the local crystallographic and hardening state of the material via integration of the evolution equations for the crystal lattice orientation and the critical resolved shear stress.
