混合稀土(La-Ce)对30MnCrNiMo钢高温变形行为的影响
|
摘要
为研究稀土对30MnCrNiMo钢高温变形行为的影响,利用Gleeble-1500D热模拟试验机对含稀土与不含稀土试验钢进行高温压缩试验并观察压缩后的显微组织。结果表明:当变形温度为1 000℃时,混合稀土(La-Ce)能够提升钢的变形抗力,并随压缩变形量的不同而不同;1 100℃时,稀土对钢的变形抗力没有明显影响。加入稀土后,钢的再结晶激活能提升了6.78%,混合稀土(La-Ce)对钢的再结晶具有抑制作用;用Origin8.0软件进行回归分析,建立含稀土30MnCrNiMo钢的数学模型,该模型具有良好的曲线拟合特性,计算值与试验值基本吻合。
In order to study the effect of rare earth on behavior of high temperature deformation of 30MnCrNiMo steel,the hot compression experiments of steel with Re and without Re were carried out by the Gleeble-1500 D thermal machine and the compressed microstructure of test steel was observed. The results show that the mixed Re(La-Ce)can enhance deformation resistance of test steel at 1 000 ℃ termperature and the effect is different at different compression deformation,while the effect of Re on deformation resistance of steel is not obvious at 1 100 ℃. The recrystallization activation energy of steel was increased by 6.78% after the addition of rare earth,and the mixed rare earth(La-Ce)play a role of inhibition on the recrystallization of steel.The mathematical model of 30MnCrNiMo steel with mixed Re was established by regression analysis with Origin8.0 software. It has good characteristics in fitting curves and the predicted results are in good agreement with the experimental values.
