作者用图象仪测试了材料结构中的晶粒粒径和孔径分布,并在此测试基础上,应用群于统计理论,建立了晶粒和孔径的群子分布函数.发现:函数中的参数与材料的性能有密切关系,证明了体系中晶粒和孔径分布是影响材料力学性能的重要因素.并提出了材料结构的物理模型,并认为:体系的晶粒分布均匀,镶嵌紧密,碳层成网状分布,孔洞小又少时,有利于提高材料的力学性能.
The author tested the grain size and pore size distribution in the material structure with the imager, and on the basis of this test, the group distribution function of the grain and the pore diameter was established by using the statistical theory, and found that the parameters in the function It is proved that the distribution of the grains and the pore size in the system is an important factor that affects the mechanical properties of the material, and the physical model of the material structure is proposed. The results show that the grain distribution of the system is uniform and the inlay is close, Into the network distribution, small and small holes, is conducive to improving the mechanical properties of materials.
