摘要

摘要: 采用Gleeble-3500热模拟试验机研究了06Cr23Ni13不锈钢在应变速率为0.01 s^-1条件下,不同变形温度的热变形行为,探究了变形温度对06Cr23Ni13不锈钢低重合位置点阵(CSL)晶界含量变化的影响。结果表明,06Cr23Ni13不锈钢再结晶程度随着变形温度的升高而增大,当变形温度为1 150 ℃时,显微组织再结晶程度最高,奥氏体晶粒为等轴晶。利用Channel 5对不同变形温度条件下06Cr23Ni13不锈钢特殊晶界统计发现,低∑CSL晶界含量随着动态再结晶程度的升高呈先增大后减小的趋势,在1 150 ℃达到最大值。06Cr23Ni13不锈钢低∑CSL晶界主要由∑3、∑9和∑27晶界构成。

Abstract: The hot deformation behavior of the 06Cr23Ni13 stainless steel at different deformation temperatures and strain rates of 0.01 s^-1 is studied by Gleeble-3500 instrument, and the effect of deformation temperature on grain boundary content of low coincidence lattice (CSL) is investigated. The results show that the recrystallization degree of the 06Cr23Ni13 stainless steel increases with the increase of deformation temperature. When the deformation temperature is 1 150 ℃, the recrystallization degree of microstructure is the highest, and the austenitic grain is equiaxed. According to the statistics of special grain boundaries of the 06Cr23Ni13 stainless steel under different deformation temperatureby Channel 5 software, the content of the low ∑CSL grain boundaries increases firstly and then decrease with the increase of the dynamic recrystallization degree during the hot deformation process, which reaches its maximum at 1 150 ℃. The low ∑CSL grain boundaries of the 06Cr23Ni13 stainless steel are mainly composed of ∑3, ∑9 and ∑27 grain boundaries.
