英文摘要
Based on experimental studies on grain boundary diffusion and segregation, we are able to show the negligible role of grain boundaries on chemical evolution of the earth interior. Further, using our accumulated knowledge of grain boundary properties, we are able to demonstrate superplasticity of the minerals and to propose grain growth law as a function of mineral fractions.
