Q345钢在直轧过程中二相粒子析出对奥氏体晶粒的影响

Precipitate Effect on Austenite Grains of Steel Q345 in Direct Hot Rolling

    摘要
  • 摘要: 通过热模拟轧制技术,研究了不同工艺条件下二相粒子析出物对奥氏体再结晶的影响,并对Q345钢直接轧制工艺中C,N化物的析出对组织性能的影响进行了深入探讨.结果表明,利用二相粒子析出可以细化奥氏体晶粒组织,从而改善钢的内部组织和材料的力学性能.

     

    Abstract: Precipitation effects on austenite recrystallization were studied with Gleeble 1500 in the traditional rolling and the direct hot rolling. The influence of the precipitation of C, N on the microstructure and properties was investigated in the direct rolling of Q245 steel. It can be concluded that the precipition of C,N could fine the austenite grain size and improve the microstrutre and properties of steel.
