| 摘 要： | 研究了45钢亚温淬火组织与性能,分析了显微组织与性能的关系.结果表明:在740～820℃,随淬火温度升高,45钢淬火组织中铁素体量逐渐减少:其分布形态也南块状、网状变成细小颗粒状,材料的综合性能得以改善.实验得出,最合理的亚温淬火工艺是(790±5)℃淬火,(550±10)℃回火.

| Abstract: | The microstructure and properties of 45 steel after subcritically-quenching were studied.The relationship between the microstructure and properties were discussed.The results show that the ferrite contents of 45 steel quenched microstructure decrease gradually in the temperature range of 740 ～820 ℃ and ferrite distributing form changes from block,mesh into a small mesh granular in 45 steel quenched microstructure.General properties of materials improve.The experiment obtains the most reasonable subcritical quenching process:quenching at 790 ℃ for 5 h,tempering at 550 ℃ for 10 h. |
