Cu–1.0Cr–0.1Zr　alloy　strips　were　prepared　by　solution,　cold　rolling　and　aging　processes.　The　effects　of　aging　process　on　the　conductivity,　mechanical　properties　and　microstructure　of　the　alloy　were　studied,　and　the　precipitation　kinetics　was　analyzed.　The　results　showed　that　the　Cu–1.0Cr–0.1Zr　alloy　exhibited　the　best　comprehensive　properties　after　aging　at　430　°C　for　180　min,　with　an　electrical　conductivity　of　85.86%　IACS,　a　hardness　of　HV　176.54,　and　a　tensile　strength　of　552　MPa.　For　the　samples　aged　at　430　°C　from　30　to　180　min,　the　fcc-Cr　and　Cu8Zr3　phases　grew　from　~5　to　~8　nm,　and　the　relationship　between　the　precipitates　and　matrix　changed　from　coherent　to　semi-coherent.　In　addition,　the　rod-like　and　spherical　coarse　particles　(≥300　nm)　of　bcc-Cr　phase　were　observed.　The　precipitation　kinetics　equations　at　different　aging　temperatures　were　established,　the　time–temperature–transformation　(TTT)　curve　was　plotted,　and　the　precipitation　activation　energy　was　obtained　as　65　kJ/mol.　©　2023　The　Nonferrous　Metals　Society　of　China
