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

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