Effects of distributions of growth rates on recrystallization kinetics and microstructure

The effects on recrystallization kinetics and microstructure of growth rate distributions rather than a single growth rate for recrystallizing grains were investigated by geometric simulations. The grains were set to grow as spheres with radii r = At1−α. The results show that distributions in A and α may produce significant changes in the microstructure and texture, whereas only distributions in α may change the overall evolution in kinetics represented by VV(t) by completely changing the shape of the kinetics curve.
