在研究合金的组织与结构时,弄清新相与基体间的晶体学取向关系是十分重要的。通常使用X射线衍射和电子衍射方法来研究这个关系。通过对电子衍射谱的标定来确定两相取向关系的方法在文献[1]、[2]、[3]中有详细的论述。应当指出,使用选区电子衍射的方 When studying the microstructure and structure of alloys, it is important to understand the crystallographic orientation between the new phase and the matrix. X-ray diffraction and electron diffraction methods are often used to study this relationship. The methods for determining the orientation of two phases by the calibration of electron diffraction spectra are discussed in detail in [1], [2] and [3]. It should be noted that the use of selected area electron diffraction side
