Phase Field Simulation of Microstructure Evolutions in the Heat Affected Zone of a Spark-Eroded Workpiece (Ergebnisse aus der Produktionstechnik)

Inhaltsangabe

In this work the induced microstructure evolution in the HAZ of a workpiece during EDM in relationship to the thermal loads are investigated experimentally and simulatively. Therefore, a phase field model for simulation of this evolution was developed. The thermal loads were calculated by heat transformation simulation and used as boundary conditions of the phase field simulation. The result of models both heat transformation simulation and microstructure evolution model were validated.
