摘要(Abstract)：

采用Gleeble-3500C热力模拟试验机研究了EH690海洋工程用高强钢在不同升温和冷却过程中的相变行为。采用切线法、金相法和硬度法分析了连续冷却过程中EH690高强钢的组织转变规律。结果表明：升温速率增大会使得EH690高强钢奥氏体相变开始和结束温度点升高，升温速率增大至一定范围后影响逐渐减小；缓慢冷却时(≤0.1℃),奥氏体主要发生铁素体转变并伴有少量贝氏体相形成；冷却速率介于0.5～5℃/s时，主要发生贝氏体相变；快速冷却时(≥10℃/s)主要发生马氏体相变。最后采用杠杆定律对热膨胀曲线进行线性回归分析，得到了用于描述奥氏体相变过程的Kamamoto模型和马氏体相变过程的Koistinen-Marburger(K-M)模型的动力学参数。
