The effect of grain-boundary orientational anisotropy on growth kinetics is examined within the context of stochastic theories of grain growth. Grain growth is characterized by power laws of the type, l∝(Formula presented), where l is some linear dimension measuring grain size and t is the time. In the case of normal grain growth the growth exponent is 0.5. It is shown that grain-boundary anisotropy leads to a slower growth kinetics with an anomalous exponent of 0.25 in agreement with Q-state Potts models of grain growth.
