【Abstract】 The dual\|phase (α+γ) intercritical heat treatment process and the structure and mechanical properties of atmospheric corrosion resistant steel 09CuPTiRE after dual\|phase treatment have been studied. The results showed that the dual phase structure with different percentage of martensite was obtained as the atmospheric corrosion resistant steel 09CuPTiRE was quenched in (α+γ) dual\|phase field (760～820 ℃) at different temperature and with quenched temperature increasing the martensite content and the strength of dual\|phase steel increased.更多还原
