以8Cr4Mo4Ni4V轴承钢为研究对象,通过奥氏体等温保温实验,研究加热温度和保温时间对奥氏体晶粒尺寸的影响,采用平均截点法对不同热处理条件下的晶粒尺寸进行统计分析。结果表明:随着加热温度和保温时间的增加,奥氏体晶粒尺寸逐渐增大,当加热温度超过1100℃或保温时间超过120min时,实验钢晶粒开始发生显著粗化。当加热温度超过1150℃时晶粒已完全粗化。通过线性回归的方法,获得了8Cr4Mo4Ni4V轴承钢的奥氏体晶粒尺寸随加热温度和保温时间演化的数学模型,为指导航空轴承钢锻造与热处理过程提供理论依据。 |

Taking 8Cr4Mo4Ni4Vbearing steel as the experimental material,the effect of heating temperature and holding time on austenite grain size was studied by austenite isothermal experiment.The grain size under different heat treatment conditions was measured by using linear intercept method. The results show that with the increase of heating temperature and holding time,the austenite grain size increases gradually.When the heating temperature exceeds 1100℃ or the holding time is over 120min,grain coarsening begins to occur.When the heating temperature exceeds 1150℃,grains become coarsened completely. The mathematical model of the austenite grain growth of 8Cr4Mo4Ni4Vbearing steel with the heating temperature and holding time is obtained by linear regression, which can provide a theoretical basis of forging and heat treatment process for the 8Cr4Mo4Ni4Vaviation bearing steels. |
