| 摘 要： | 通过热模拟试验,研究了Nb微合金钢中的碳氮化析出物在高温及低温等温过程中的析出行为.试验结果表明:在高温时,应变诱导NbC析出需要一定的孕育时间.随着高温等温温度的升高,析出物的数量增多.当高温等温时间达到300 s时,单一析出转变为复合析出,同时随着温度的升高,复合析出聚合长大,数量明显减少,形状变为不规则形状;在低温时,随着等温温度的升高,析出数量略有增多.随着等温时间的延长,析出物的数量略有增多,尺寸略有增大. |
| 关 键 词： | Nb微合金钢 碳氮化物 应变诱导析出 复合析出 |

| Abstract: | Carbonitride precipitation behavior of Nb microalloyed steel during holding at high temperature and low temperature was studied through thermal simulation.The results show that in high temperature region incubation period is necessary for strain induced NbC precipitation,and increasing the holding temperature leads to an increase of precipitation.Simple precipitation changes to complex precipitation when holding for 300 s at high temperature.Meanwhile,complex precipitation converges and grows,the amount of ... |
