Analysis and Research on the Microstructure Fractal Characteristics of the Copper Matrix Composites

摘要

Through the analysis and research on images of microstructure of the copper matrix composites, we calculated the fractal dimension of images of microstructure on cross section and parallel pressed power side under different experimental conditions. Meanwhile analyzed some statistics characteristics of fractal dimension. The results show that fractal dimension of graphite reflects the distribution, the dimension is more larger, the organization chart is more complex, the distribution of graphite is more irregular, so the irregular distribution of free graphite can be described by fractal dimension, fractal dimension can be used as a material characterization parameters of organizational form. Through analyses we can get that the fractal dimension of the materials on cross section and parallel pressed power side combining to normal distribution, and it changed with graphite content doesn't affect each other.
