Utilizing multi-scale characterization methods,including Energy Dispersive Spectroscopy(EDS),Transmission Electron Microscopy(TEM),and Electron Backscatter Diffraction(EBSD),the effects of varying degrees of cold rolling deformation and aging treatments on the microstructure of the C18150 alloy were investigated.Throughout the process,the mechanical and electrical properties were systematically analyzed.The results indicate that increasing levels of cold rolling deformation and aging treatments elevated the alloy's hardness from 141.0 HV to 183.9 HV and 186.5 HV,respectively,and enhanced its electrical conductivity from 49.8％IACS to 77.1％IACS and 82.7％IACS.EBSD revealed a gradual reduction in grain size on the side.Post-treatment,the deformation texture strength of the samples increased,the proportion of the Brass texture rose,and the distribution of geometrically necessary dislocation density became more uniform.The number of precipitated phases increased,exhibiting ellipsoidal and elongated rod-like shapes,with the average size gradually decreasing.The precipitate phases transitioned from a semi-coherent relationship to a coherent relationship with the matrix.
