摘要/Abstract

摘要： 利用光学显微镜(OM)、扫描电镜(SEM)和透射电镜(TEM)研究了T23钢及4组改进型T23钢CGHAZ的微观组织,采用Gleeble热模拟及高温缓慢拉伸的方法评判T23钢和4组改进型T23钢焊接热影响区粗晶区(CGHAZ)的再热裂纹敏感性。探讨了再热裂纹敏感性的影响因素,分析了改进型T23钢再热裂纹敏感性改善的原因。结果表明,晶粒尺寸、晶界和晶内析出相以及晶内固溶元素均对再热裂纹敏感性有较大的影响。与T23钢相比,成分改进后的T23钢CGHAZ的微观组织得到了优化,晶界晶内强度差减小,再热裂纹敏感性得到改善。

Abstract: Microstructure of CGHAZ in T23 and four groups of modified T23 steel was investigated by means of optical microscope (OM), scanning electron microscope (SEM) and transmission electron microscope (TEM). Gleeble was used to produce the simulated coarse-grained heat-affected zone (CGHAZ) in T23 and four groups of modified T23 steel via thermal simulation of welding, and it was also used to evaluate the reheat cracking susceptibility by isothermal slow strain rate tensile test. The factors that influencing reheat cracking susceptibility were discussed, and the reasons for decreased reheat cracking susceptibility of modified T23 steel were analyzed. The results show that the grain size, intergranular precipitates, intragranular precipitates and solid solution elements have a significant influence on the reheat cracking susceptibility. Compared with T23 steel, the microstructure of modified T23 steel is optimized, leading to the decreased difference between intergranular strength and intragranular strength. Therefore, the reheat cracking susceptibility of modified T23 steel is improved.

Key words: modified T23 steel, reheat cracking susceptibility, Gleeble thermal simulation, coarse-grained heat-affected zone (CGHAZ), precipitates
