2-DIMENSIONAL GRAIN-GROWTH MODEL CONSIDERING THE EFFECT OF TEXTURES

A new statistical model for 2-dimensional grain growth has been developed with the method of integrating the migration rate along grain boundaries. The specific energy gamma and the mobility m of a grain boundary is considered as being dependent on the orientations of the grains on both sides of the boundary, so that a comprehensive understanding of the effect of textures on the process of grain growth can be obtained. With the new model some experimental results of texture controlled grain growth can be interpreted satisfactorily.
