| 摘 要： | 利用Gleeble模拟技术研究了不同N含量和热加工工艺对N80无缝管(33Mn2V成分)的影响.结果显示,在各种工艺条件下,N含量从0.005%增加至0.014%或0.021%,在保持钢的强度提高的同时,钢的韧性也显著增加.进一步研究表明,当降低再加热温度时,钢的强度略微损失,韧性提高;而钢的中间停冷温度从450℃提高至700℃,工艺从在线常化变化为非在线常化,则使钢的强度有较大提高的同时韧性明显降低.无缝管的上述力学性能变化和V在钢中的溶解和析出行为以及相应的显微组织变化有直接关系.N含量的增加则优化了V(CN)的析出行为.

| Abstract: | The synthesis effects of different nitrogen(N) contents and thermal processes on the microstructure and mechanical properties of 33Mn2V steel for N80-class seamless tube were investigated using Gleeble simulation technique.The results showed that when the N content in the steel increased from 0.005% to 0.014% or 0.021%,for in-line normalizing process,the strength of steel increased,and in the same time toughness of steel increased greatly.The further research showed that while the reheating temperature decr... |
