发现了多晶马氏体x射线衍射的实验规律，并从x射线衍射理论对其进行了满意的解释。实验结果与低碳马氏体为立方结构的假设相吻合。观察了与碳原子分布有关的马氏体的立方-四方转变，并得到了该转变的实验临界点。建立了低碳马氏体晶格参数与碳含量的关系。有了这些依赖关系，就可以测定钢中碳过饱和α相的含碳量。
An experimental law of the x-ray diffraction of polycrystalline martensite is found, which is satisfactorily explained from x-ray-diffraction theory. The experimental phenomenon is well consistent with the hypothesis that at low carbon content martensite is of cubic structure. The cubic-tetragonal transition of martensite concerned with the distribution of carbon atoms is observed, and an experimental critical point of the transition is also obtained. Dependences of the lattice parameter of low-carbon martensite upon carbon content are established. With the dependences, it becomes possible to determine the carbon content of the carbon-supersaturated alpha-phase of steel.
