摘要/Abstract

摘要： 通过试验研究了20CrMnTi钢和20钢在不同保温温度(1000~1200 ℃)和不同保温时间(0~300 s)条件下的奥氏体晶粒长大行为,并基于试验结果建立了描述奥氏体晶粒长大行为的Sellars数学模型。通过对比两种钢的奥氏体晶粒长大模型计算值与试验值的平均相对误差(AARE)和相关系数(R),验证了模型的可靠性。试验与模拟结果表明,随着加热温度的升高,试验钢晶粒尺寸都有明显的增加;随着保温时间的延长,在前60 s晶粒尺寸增长快速,之后增速减缓。但在相同试验条件下,20CrMnTi钢的奥氏体晶粒尺寸都明显小于20钢,且没有出现晶粒异常长大现象,说明Ti元素的添加具有明显细化组织的作用。

Abstract: Austenite grain growth behavior of 20CrMnTi steel and 20 steel under different holding temperatures (1000-1200 ℃) and different holding time (0-300 s) was studied. Based on the experimental results, a Sellars model describing austenite grain growth behavior was established. By comparing the average relative error (AARE) and correlation coefficient (R) between the calculated values of austenite grain growth model and the experimental values, the reliability of the model was verified. The experiment and simulation results show that the grain size of the steel increases obviously with the increase of heating temperature, and increases rapidly in the first 60 s with the increase of holding time, and then slows down. However, under the same test conditions, the austenite grain size of the 20CrMnTi steel is obviously smaller than that of the 20 steel and no abnormal grain growth occurs,indicating that the element addition of Ti has obvious effect on refining the microstructure.

Key words: 20CrMnTi steel, 20 steel, austenite, grain growth, Sellars model
