Adaption of new strategies for parameterization of a microstructure-based flow stress model

One of the most important tools in the metal forming technology is the integrated process and microstructural simulation using Finite Element Methods (FEM). It has become more and more popular in recent years, especially in the segment of hot metal forming, e.g. open die forging of large scaled and hardly deformable materials, such as nickel-based super alloys for turbine shaft. Theoretically using this method it is possible to calculate the microstructural evolution along the whole process c…
