Interface relation database construction method and device

The invention provides an interface relation database construction method and device. The method comprises the steps that a two-phase crystal structure model is collected; determining a two-phase crystal face library according to the two-phase crystal structure model; selecting two-phase crystal faces according to the two-phase crystal face library; calculating an interface mismatch degree according to the two-phase crystal face; judging an interface relationship according to the mismatch degree; and constructing an interface relationship database according to the interface relationship. According to the method, a two-phase crystal face library is established, the mismatch degree of corresponding interfaces of two-phase crystal faces is calculated, and the corresponding interface relationship is judged, so that an interface relationship database is constructed. 本发明提供一种界面关系数据库构建方法及装置，该方法包括：获取两相晶体结构模型；根据两相晶体结构模型确定两相晶面库；依据两相晶面库选取两相晶面；根据两相晶面计算界面错配度；依据错配度判断界面关系；根据界面关系构建界面关系数据库。本发明通过建立两相晶面库，计算两相晶面对应界面错配度，判断对应界面关系，从
