摘要
研究Q345R低合金钢在连续冷却过程中奥氏体的相变行为及其在非恒定冷速空冷组织分析中的应用。结果表明,和温度-时间(T-t)曲线相比,冷速路径(T-v)曲线能够更加准确、直观地反映相应温度下的实际冷速,将冷速路径和CCT图叠加分析得到的转变组织和实际冷却组织相符。
This paper studies the austenite phase change behavior of Q345R low alloy steel and its application in analysis of non-constant cooling rate air cooling structure.The results show that compared with temperature-time(T-t)curve,cooling rate path(T-v)path can reflect more accurately and directly the actual cooling rate,and the transformation structure obtained from analysis by overlay of cooling rate path and the CCT diagram is in line with the actual cooling structure.
