摘要/Abstract

摘要： 为了降低绘制CCT曲线的成本和得到更加准确的相变量计算模型用于预测大型工件的性能和残余应力分布,使用Li模型预测A668钢的CCT曲线,再根据预测的结果制定适量且关键的试验组,完成制定的相变膨胀试验之后用试验结果修正预测模型,最后用模型计算出完整和准确的CCT曲线。使用DIL-805-ADT动态淬火膨胀相变仪确定了不同冷速下的转变类型和转变量,比较了JMatPro软件和原模型计算的结果与试验结果的差别,阐述了修正扩散转变预测模型和绘制CCT曲线的过程,拟合了非扩散转变的K-M方程,说明了不同冷速和组织演变之间的关系。最终得到更加准确的预测模型和完整的CCT曲线来指导实际生产。

Abstract: In order to reduce the cost of drawing CCT curves and obtain more accurate calculation models of phase transformation to predict the properties and residual stress distribution of large components, the Li model was used to predict the CCT curves of A668 steel, and an enough and essential experimental group was developed based on the predicted results. After completing the phase transformation expansion experiment, the experimental results were used to correct the prediction model and the new model calculated the complete and accurate CCT curves. According to the expansion curves and metallographic results measured by DIL-805-ADT phase transformation dilatometer, the transformation type and transformation volume at different cooling rates were determined. The difference between the results which was calculated by original model and JMatPro software and the experimental results were compared. The process of modifying the prediction model and drawing the CCT curves was described. K-M equation for calculating martensite transformation was fitted. The relationship between different cooling rates and phase transformation was illustrated. A more accurate predictive model and complete CCT curves were obtained to guide actual production.
