Research on the Microstructure Fractal Characteristics of Copper Matrix Composites
Through the analysis and research on the Microstructure of copper matrix composites,according to the fractal theory,calculated microstructure friction dimension of cross section and parallel pressed power side of copper matrix composites under different experimental conditions.The results show that,for parallel pressed power side,fractal dimension reflects the distribution laws of graphite in the sample,the fractal dimension is more larger,the organization chart is more complex,the distribution of graphite is more irregular,so the irregularity of graphite distribution can be described by fractal dimension,fractal dimension can be used as a characterization parameter of organizational form for copper matrix composites.Under the condition of virtually expanded sample,in the view that Sn,Zn and SiO2 is not changed respectively,and the sum of Cu and graphite is 85%,by use of linear regression model to estimate parallel pressed power side of microstructure fractal dimension of different composition in copper matrix composites.
