Numerical Simulation of Thermomechanical Processes Coupled with Microstructure Evolution

The finite element method is a consolidated tool used in the metal-forming field at an industrial scale. However, further progress is needed regarding the microstructure optimization of components produced by metal-forming processes such as hot forging or rolling. This article presents mathematical models to predict microstructure evolution during hot working, showing an application of mathematical models coupled to a thermomechanical processes' simulation software.
