Research Progress in Precipitation Crystallography models
沉淀相变晶体学模型的研究进展

In-depth understanding of precipitation crystallography is very essential to the control of microstructure in many multi-phases materials. The present paper reviews the recent development of various crystallographic models. Each model was reviewed in terms of its hypothesis, applicable scope, basic idea, and especially its limitation. According to the comparison and contrast between different models, it is proposed that combining the O-line model and near coincidence sites model may provide a more powerful tool to interpret the precipitation crvstallography and morphology.
