| 摘 要： | 研究了真空感应炉(6.5 kg锭)熔炼的00Cr25Ni7Mo4N钢(%:0.007～0.009C、24.50～24.84Cr、6.92～6.99Ni、3.65～3.72Mo、0.27～0.30N)的相比例和固溶处理温度对钢的组织和力学性能的影响。结果表明,随固溶温度由1 050℃增至1 200℃,钢中铁素体含量由48%～50%提高至53%～55%。当固溶温度由1 050℃提高至1100℃,钢的强度下降,伸长率和冲击韧性增加,当固溶温度由1 100℃提高至1 200℃,钢的强度增加,伸长率和韧性降低,该钢最佳固溶温度为1 100℃±50℃。

| Abstract: | Effect of phase proportion and solution temperature on structure and mechanical properties of steel 00Cr25Ni7Mo4N ( % ： 0. 007 ~0.009C, 24. 50 ?24. 84Cr, 6.92 ?6.99Ni, 3.65 ?3. 72Mo, 0. 27 ~0. 30N) melted by vacuum induction furnace (6. 5 kg ingot) has been studied. Results showed that with increasing solution temperature from 1 050 °C to 1 200 °C , ferrite content in steel increased from 48% ?50% to 53% ?55% ; with increasing solution temperature from 1 050 °C to 1 100 °C , the strength of steel decreased while the elongation and impact toughness of steel increased ,and with increasing the solution temperature from 1 100 °C to 1 200 °C , the strength of steel increased while the e- longation and impact toughness of steel decreased, so optimum temperature of the steel was 1 100 °C ±50°C. |
