连铸无磁辊用X5NiCrTi2615MoAlVB钢中时效析出相的长大动力学
|
摘要
将一种新型连铸无磁辊用X5NiCrTi2615MoAlVB钢在1 000℃固溶处理后,再分别在660,710,760,810℃下时效0~30h,利用扫描电镜观察其析出相的形貌;然后利用Photoshop和Image-Pro Plus软件计算并统计其析出相的平均尺寸,研究了时效过程中γ′相的长大动力学。结果表明:试验钢在660~810℃时效处理0~30h后,均析出了大量白色的圆形γ′相,且随时效时间延长,γ′相的尺寸不断增大;γ′相在0~2h内迅速长大,之后其长大速率逐渐减小;在相同的时效时间下,时效温度越高,γ′相的平均尺寸越大;拟合得到的γ′相的平均尺寸与实际测量值之间的误差在10%以内。
Scanning electron microscope was used to observeγ′phase in new non-magnetic roller steel X5NiCrTi2615 MoAlVB which was treated by solid-solution at 1 000 ℃ and followed by aging 0-30 hat 660,710,760,810 ℃.And then,the softwares of Photoshop and Image-Pro Plus were used to calculate the average size ofγ′phase,and thus to study the kinetics of precipitate growth during aging process.The results show that after aging0-30 hat 660-810 ℃,a lot of white and circularγ′phases precipitated;With the increase of aging time,the size ofγ′phase increased gradually;In 0-2h,γ′phase grew up rapidly,and after that,the growth rate ofγ′phase gradually decreased;Under the same aging time condition,the higher the aging temperature,the larger the average size ofγ′phase.Fitted values of average size ofγ′phase were satisfied with the measured ones,the error between them was less than 10%.
