摘　　要：研究了 Si、Mn含量对 10 Si Cr Ni Cu钢综合性能的影响。研究结果表明 :Si含量从 0 .95 %降低到 0 .40 %～ 0 .70 %、Mn含量从 0 .6 5 %提高到 1.30 % ,钢的强度指标满足σs≥ 390 MPa的设计要求 ,冲击转变温度明显降低 ,在低温下 ,能够表征材料抗脆断能力之一的裂纹扩展功显著提高。The effect of content of Si,Mn on the comprehensive property of 10SiCrNiCu is studied. The results show that the strength index of the steel satisfied with the design request ,which σ s is more than or equal to 390MPa.The content of Si in this steel decreases from 0.95% to 0.40~0.70% and the content of Mn increases from 0.65% to 1.30%.The impact transformation temperature of the steel decreases greatly. The work of crack propagation is improved greatly under low temperature, which is one denotation of material 's anti-brittle fracture ability.
