摘要:
通过建立模拟焊接热循环的热力学和动力学(ТКД)模型,研究了X80,K70和X90三种强度级别管线钢焊接热影响区(HAZ)奥氏体相变,探讨了最高加热温度和冷却速度对焊接热影响区组织与性能的影响以及硬度与冷却速度的关系。研究结果表明:三种强度管线钢相比,X90钢中Ni,Cu和Mo含量较高,导致奥氏体相变温度降低,从而使组织硬度较高;当冷却速度超过35 ℃/s时,熔合线附近形成较高硬度的马氏体组织,焊接时X90钢中可能产生冷裂纹;建立焊接热循环的热力学和动力学模型法可用于预测大直径钢管焊接时热影响区不同部位组织的形成情况。
Abstract:
The study on the austenite phase transformation in Hot Affected Zones(HAZ) of these pipeline steel grades such as X80, X90 and K70 based on making the model of thermodynamics and dynamics charts(ТКД)by simulation of weld thermal cycle is carried out by Igelsk Steel Pipe Mill of Severstal together with Prometheus Central Research Institute for Structural Materials, Russia. The effect of the maximum reheating temperature and cooling rate on microstructure and mechanical property in HAZ is discussed and then the relationship between hardness and cooling rate is analyzed by taking the cold crack and softening trend of these mentioned pipeline steels as important indexes.
