摘　　要：应用光学显微镜及力学性能测试设备,研究了不同正火温度和保温时间对80 mm E36钢板组织性能的影响。结果表明:随着正火温度的升高,钢板强度降低,抗拉强度降幅大,冲击值大幅增加;相同正火温度下,延长保温时间,力学性能变化不明显。此类钢板的最佳正火工艺是920℃+80 min的正火。Performance variation of 80 mm hull plates grade E36 at two normalizing temperature are analyzed through the application of optical microscope and mechanical test equipment. The results show that, the strength and tensile strength drop and impact value greatly increase with the normalizing temperature increasing. At the same normalizing temperature, if prolong the heat preservation time, changing of mechanical properties is not obvious. This best normalizing process is normalized at 920 ℃ holding 80 minutes for this kind of steel plate.
