自从劳厄等在1912年发现X射线衍射现象后,到现在已有七十余年历史。在过去的七十多年中,有关X射线衍射(包括散射)的理论、设备、方法及应用等都有很大的发展,现已渗透到物理、化学、地学、生命科学及各种工程技术科学。对于冶金学及材料科学的发展,更起到了极其有益的作用。X射线衍射方法,是进行各种冶金原料,中间产物、半成品和成品,炉渣、烟尘中物相的定性及定量分析不可缺少的测试手段,从而可以有 Since Laueu et al discovered the phenomenon of X-ray diffraction in 1912, it has been more than seventy years old. Over the past seventy years, the theory, equipment, methods, and applications of X-ray diffraction (including scattering) have greatly developed and now have penetrated into physics, chemistry, geosciences, life sciences and various engineering technologies science. For the development of metallurgy and materials science, has played an extremely beneficial role. The X-ray diffraction method is an indispensable test method for the qualitative and quantitative analysis of the phases of various metallurgical raw materials, intermediate products, semi-finished products and finished products, slag and soot so as to have
