The grain microstructure is an important feature of polycrystalline solids. The control of the microstructure is a key to improve the material's properties in processing, like e.g. strength, toughness, diffusivity and electrical conductivity. Therefore, it is very important to predict the grain microstructure and its time evolution due to processes like recrystallization and grain growth. Some basics of the grain structure of polycrystalline materials and especially the phenomenon of grain growth are shortly outlined (Chapter 2). In particular, the basic properties and fundamental equations are presented setting a theoretical frame for the investigation of the results of the simulation data and for the theoretical investigations.weiterlesen
