Microstructure and Conductivity Analysis of CuAl2O3/Fe Matrix Composites Prepared by Vacuum Sintering
The CuAl2O3 electronic material was prepared by vacuum sintering process,and the conductivity of the alloy was improved by adding Fe powder.The microstructure and conductivity of CuAl2O3/Fe alloy were analyzed by means of experimental test.The results showed that the CuAl2O3 alloy sample with excellent high temperature resistance was prepared,and the peak strength of CuAl2O3 decreased with the increase of Fe addition.A high-light structural phase with iron as the main component was formed,while CuAl2O3 showed a dark structure,and a large number of microholes were generated in the alloy.When the iron content is low,the reactance and conductivity characteristics are not obvious.In the case of higher iron content,significant resistance characteristics and higher conductivity are obtained.It can be seen that adding Fe is helpful to improve the electrical conductivity of CuAl2O3 alloy.This study is helpful to improve the conductive properties of copper alloys and lay a theoretical foundation for the subsequent optimization of metallurgical properties.
