摘要/Abstract

摘要： 利用热模拟试验机研究了3种不同成分的Nb、V微合金化高钢级管线钢的过冷奥氏体连续冷却转变行为,绘制了动态CCT曲线,分析和比较了3种试验钢的显微组织、显微硬度值和动态CCT曲线。结果表明,0.05Nb-0.03V配比能提高多边形铁素体的开始转变温度,从Nb钢的650~700 ℃,提高到700~800 ℃,并缩小多边形铁素体温度转变区间,扩大贝氏体温度转变范围,从Nb钢的400~650 ℃,扩大到350~680 ℃,同时抑制多边形铁素体相变,使管线钢更易获得所需的贝氏体针状铁素体组织。

Abstract: Continuous cooling transformation behavior of subcooled austenite of three different Nb, V microalloyed high-grade pipeline steels with different composition was studied by using thermal simulation test machine, dynamic CCT curve was drawn, and three tested steels were analyzed and compared. The microstructure, microhardness value and dynamic CCT curve. The results show that the ratio of 0.05Nb-0.03V can increase the starting transformation temperature of polygonal ferrite, from 650-700 ℃ for Nb steel to 700-800 ℃, narrowing the temperature transition range of polygonal ferrite, and expanding bainite temperature transformation range of Nb steel is 400-650 ℃, and it is expanded to 350-680 ℃. At the same time, the polygonal ferrite phase transformation is suppressed, so that the pipeline steel can easily obtain the required bainite acicular ferrite structure.

Key words: Nb-V microalloyed steel, pipeline steel, dynamic CCT curve, secondary phase precipitation
