【摘要】 <正> 相邻两晶粒间的位向关系是描述晶界几何结构的重要参数之一。目前,主要的实验方法是:X射线衍射法,电子衍射法,菊池花样法等几种。应用这些方法所得的结果,再结合数学上求矩阵的方法,就可确定两晶粒间的位向差、回转轴和晶界面的位向关系等。更多还原

【Abstract】 A method is described using the etch-pits technique for the experimental determination of the geometric structure of the grain boundary. The orientation relations between both sides of the grain boundary can be directly determined and the atomic configuration along the grain boundary can be easily drawn in theory. Owing to its simplicity, this technique seems to be available to accumulate the experiential patterns of various boundary structure.更多还原
