by mimicking the commercial process. The mechanical and electrical properties of C70250 alloy were analyzed under hot rolling state, aging after hot rolling and aging after cold rolling following hot rolling. The effects of quenching and cooling by radiation on the mechanical properties were also investigated. The results show that aging precipitation is the primary strengthening method for the C70250......
