热轧船板钢时奥氏体相变的规律

Phase Transformation of Austenite in the Hot Rolling of Ship Plate Steel

摘要: 通过对现场轧制工艺的模拟,借助热加工模拟试验机研究了变形量、变形温度及变形后的冷却速度,对一般强度船板钢变形奥氏体向铁素体和珠光体转变的影响。实验结果表明:增加变形量,降低变形温度,减缓冷却速度可在不同程度上促进奥氏体向铁素体和珠光体的转变。

Abstract: Based on the experiment which is made by simulating rolling parameters in site, transformation of formed austenite to ferrite and pearlite related to strain, temperature and cooling rate has been discussed in the paper. The results show that more strain, higher temperature and lower cooling rate can promote, to a different content, the transformation of both ferrite and pearlite from formed austenite.
