   	field :abstract, default: "The concept of microstructure engineering has gained increasingly attention with the goal to quantitatively link the operational parameters of an industrial process to the properties of its product. The key component of this concept is to accurately model the microstructure evolution along the processing path. Modelling of recrystallization in Cuinterconnects will be presented as an example of a conventional process model. Further, the potential of developing next generation process models will be discussed by using models across different length and time scale. The multi-scale modelling approach will be illustrated with a case study for phase transformation in Fe-Mn alloys."
