摘要/Abstract

摘要： 以海洋平台用钢EH36为研究对象,采用DIL805L淬火膨胀仪模拟试验钢的焊接过程,通过热膨胀法结合金相法与维氏硬度测试,建立了试验钢的SHCCT曲线,研究了不同冷却速率对焊接热影响区的组织转变规律显微组织与硬度的影响。结果表明,在整个冷速范围内,试验钢热影响区主要发生了铁素体+珠光体、铁素体+珠光体+贝氏体、贝氏体、马氏体+贝氏体4种类型的组织转变,且硬度值随冷速增加由164 HV10增加到277 HV10,当冷速低于5 ℃/s时,试验钢热影响区硬度低于母材;为保证试验钢获得良好的焊接接头性能,应控制冷速在10~20 ℃/s(即t_8/5时间控制在15~30 s)范围内。

Abstract: Offshore platform steel EH36 was taken as the research object, and the welding process of the tested steel was simulated by DIL805L quenching dilatometer. The SHCCT curve of the tested steel was established by means of thermal expansion method combined with metallography method and Vickers hardness test, and the influence of different cooling rates on the microstructure transformation law of the welding heat affected zone was studied. The results show that in the whole cooling rate range, there are four types of microstructure transformation in the HAZ of the tested steel: ferrite+pearlite, ferrite+pearlite+bainite, bainite and martensite+bainite, and the hardness value increases from 164 HV10 to 277 HV10 with the increase of cooling rate. When the cooling rate is lower than 5 ℃/s, the hardness of the HAZ of the tested steel is lower than that of the base metal. In order to ensure that the tested steel obtains good welding joint properties, the cooling rate should be controlled in the range of 10-20 ℃/s (that is, the t_8/5 time is controlled in the range of 15-30 s).
