| 摘 要： | 试验了890～930℃淬火、400～440℃回火时淬-回火温度对160mm×160mm连铸坯轧成的Φ21mm 60Si2CrVAT弹簧钢组织和力学性能的影响。结果表明,910℃淬火.回火后的60Si2CrVAT钢抗拉强度高于890℃和930℃淬火-回火钢的抗拉强度,不同淬火温度下钢的抗拉强度随回火温度升高而降低。分析了拉伸断口的组织形貌。

| Abstract: | The effect of quenching and tempering temperature of Φ21 mm finished products rolled by 160 mm×160 mm concasting billet of spring steel 60Si2CrVAT quenched at 890~930 ℃ and tempered at 400～440 ℃ on structure and mechanical properties of steel has been tested. Results showed that the tensile strengh of tempered spring steel 60Si2CrVAT quenched at 910 ℃ was higher than that quenched at 890 ℃ and 930 ℃,and with increasing tempering tem perature the tensile strength of steel quenched at different temperature decreased. The structure morphology of tensile frac ture was analyzed. |
