摘要
研究了淬火和回火温度对低合金钢组织和力学性能的影响。结果表明:890℃保温1h后油淬,250℃×2h回火后,组织为回火马氏体+残奥+少量碳化物。洛氏硬度大于50HRC,冲击韧度大于40J/cm2,且冲击试样断口为韧性断口。
The influence of quenching and tempering temperature on mechanical properties and microstructure of a sort of low alloy steel was investigated.The results show that the microstructure is tempered martensite and retained austenite and some carbide after oil quenching at 890℃×1 h and tempering at 250℃×12 h. HRC ≥50, A KU≥40J/cm^2.The impact fracture is gliding fracture.
