| 摘 要： | 对比分析了传统连杆用非调质钢F38MnVS(/%:0.37C、1.32Mn、0.18Si、0.008P、0.060S、0.12Cr、0.12V)锻坯的胀断性能和胀断连杆用非调质钢C70S6(/%:0.72C、0.57Mn、0.32Si、0.020P、0.060S、0.17Cr、0.03V)锻坯的胀断性能。结果表明,C70S6钢的胀断性能明显优于F38MnVS钢。C70S6钢的组织以片层状珠光体为主,铁素体的含量极低,胀断面以脆性断裂为主,达到胀断技术的要求。

| Abstract: | The fracture splitting properties of forged slab of microalloying steel F38MnVS(/%:0.37C,1.32Mn, 0.18Si,0.008P,0.060S,0.12Cr,0.12V) for traditional connecting rod and the fracture splitting properties of forged slab of microalloying steel C70S6(/%:0.72C,0.57Mn,0.32Si,0.020P,0.060S,0.17Cr,0.03 V) for fracture splitting connecting rod have been compared and studied.Results indicate that the fracture splitting properties of steel C70S6 are obviously better than that of steel F38MnVS.The main structure of steel... |
