| 摘 要： | 对Nb微合金化CFB/M复相钢的组织遗传规律进行了试验研究.结果表明:对Nb微合金化CFB/M复相钢进行等温处理与退火处理均能发生扩散型相变,消除淬火组织的位相关系,从而有效切断了组织遗传.另外,研究发现Nb微合金化CFB/M复相钢在相当宽的加热速率范围内存在组织遗传现象,当加热速度提高到40℃/s以上时不再出现组织遗传现象,晶粒开始细化,这与不同加热速度下加热过程中的回火程度和元素的扩散程度有关.

| Abstract: | In this paper,the rule of structural heritance in Nb-microalloyed CFB/M complex phase steel is investigated by experiments.The result shows diffusion transformation can occur and can erase the orientation relationship of martensitic structure after isothermal treatment and annealing so as to effectively cut off the structural heredity for Nb-microalloyed CFB/M complex phase steel.In addition,It shows in the experiments that the existence of structural heredity in Nb-microalloyed CFB/M complex phase steel is... |
