【摘要】 研究了淬火温度对2Cr12NiMoWV钢组织和力学性能的影响规律，分析了淬火温度对冲击韧性影响的原因，并确定了合理的淬火温度。结果表明：在同一回火温度下，经1055～1070℃温度区间加热淬火，可以获得最高的冲击韧性．更多还原

【Abstract】 The effects of quenching temperature on rnicrostructures and properties of steel 2Cr12NiMoWV havebeen studied. Reasons of effect of quenching temperature on impact ductility have been analysed,and a more reasonablequencbing temperature is recomrnended. Result indicate that at 1055～1070℃ heating and quenching,the highest im-Pact ductility can be obtained.更多还原
