![]() ![]() Laue method is one of main method of carrying out X ray monocrystalline orientation.An important link of Laue method is analyzed effectively accurately to Laue photo exactly.At document 1(" monocrystal Determination of Orientation ", " physical testing ", Fu Liang thunderclap, 1986) and document 2(" application Laue method is measured orientation and the symmetry of crystal ", " physical testing ", in old saying, 1986) in, principle and the implementation method of using Laue method to carry out monocrystalline orientation are described in detail.For cubic crystal, in some cases, in Laue photo, only need to record the position of (111) crystal face, as only required the directional cutting to (111) crystal face.Document 3(" judgement of molybdenum single crystal and the test of fleet angle thereof ", " physical and chemical inspection-physics fascicle ", thunder is novel) in mention the test of measuring molybdenum single crystal (111) high preferred orientation fleet angle, only need to consider the situation of (111) crystal face position.īefore setting forth implementation procedure of the present invention, first simply introduce back reflection Laue method principle.Fig. According to the method, the (111) crystal face is directly calibrated on the Laue photo through the coordinate paper, computing is easy, computing speed is high, and meanwhile computing errors generated in middle steps are avoided. ![]() The method comprises the steps that the Laue photo is obtained, the distance h between the Laue photo and a crystal is measured diffraction spots which belong to the same crystal face family are found on three low-index crystal belts of the Laue photo respectively a piece of coordinate paper is placed underneath the bottom of the Laue photo the Laue photo is adjusted, so that any two diffraction spots of the three diffraction spots are placed at the coordinate paper original point and in the x-axis positive direction respectively according to the coordinates of the three diffraction spots, the coordinates of the center point of the Laue photo and the distance h, the coordinates of the diffraction spots of the (111) crystal face are solved according to the coordinates of the diffraction spots of the (111) crystal face, the (111) crystal face is calibrated on the Laue photo. The invention discloses a method for calibrating a (111) crystal face on a cubic crystal back reflection Laue photo and belongs to the technical field of single crystal material orientation calibrating.
