范围：1.1 This test method covers the back-reflection Laue procedure for determining the orientation of a metal crystal. The back-reflection  Laue method for determining crystal orientation (1, 2)  may be applied to macrograins (3) (0.5-mm diameter or larger) within  polycrystalline aggregates, as well as to single crystals of any size. The  method is described with reference to cubic crystals; it can be applied equally  well to hexagonal, tetragonal, or orthorhombic crystals. 1.2 Most natural crystals have well developed external faces, and the orientation of such crystals can usually be determined from  inspection. The orientation of a crystal having poorly developed faces, or  no faces at all (for example, a metal crystal prepared in the laboratory)  must be determined by more elaborate methods. The most convenient and accurate  of these involves the use of X-ray diffraction. The “orientation of  a metal crystal” is known when the positions in space of the crystallographic 下载地址：
