Abstract:
A numerical method for modeling electrical conductivity of multi-component alloys is presented. The finite element method is employed to analyze the current field that is generated when a current flows through a conductor. The components of all finite elements are determined randomly to simulate real alloy. The equivalent electrical conductivity is calculated through summing up the total loss produced in the multi-component alloy modeled. By using the three-dimensional finite element model based on the electric scalar potential, the influences of component and porosity on the electrical conductivities of Cu-Cr and Ag-W electro-contact alloys are investigated numerically. The current field distributions corresponding to different ratios of components are also shown. The validity of the proposed model was verified through applications of the model in many practical problems, where excellent agreement between measured and calculated results was obtained.
