In this paper, the effects of different heating temperatures and holding time on original austenite grain size are studied by taking X80 pipeline steel as the research object. The results showed that the original austenite grain size of X80 pipeline steel holding for 1 hour at different heating temperatures was gradually increased with the increase of heating temperature; the austenite grain was coarsened rapidly with the effect of driving force of high grain boundary at initial stage of holding under the soaking condition of 1 180 ℃ as well as the average size was increased from 15 μm to 50 μm within 1 hour, which showed the high sensitivity to time.

文章以X80管线钢为研究对象,开展不同加热温度和保温时间对原始奥氏体晶粒尺寸影响研究。结果表明,不同加热温度保温1 h的X80管线钢的原始奥氏体晶粒尺寸随加热温度的升高而逐渐增大;在1 180 ℃均热条件下,保温初期,在高晶界驱动力的作用下,奥氏体晶粒迅速粗化,平均尺寸在1 h内由15 μm快速长大至50 μm,表现出对时间的高度敏感性。

文章以X80管线钢为研究对象,开展不同加热温度和保温时间对原始奥氏体晶粒尺寸影响研究。结果表明,不同加热温度保温1 h的X80管线钢的原始奥氏体晶粒尺寸随加热温度的升高而逐渐增大;在1 180 ℃均热条件下,保温初期,在高晶界驱动力的作用下,奥氏体晶粒迅速粗化,平均尺寸在1 h内由15 μm快速长大至50 μm,表现出对时间的高度敏感性。

In this paper, the effects of different heating temperatures and holding time on original austenite grain size are studied by taking X80 pipeline steel as the research object. The results showed that the original austenite grain size of X80 pipeline steel holding for 1 hour at different heating temperatures was gradually increased with the increase of heating temperature; the austenite grain was coarsened rapidly with the effect of driving force of high grain boundary at initial stage of holding under the soaking condition of 1 180 ℃ as well as the average size was increased from 15 μm to 50 μm within 1 hour, which showed the high sensitivity to time.
