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

    Graphical Abstract
    • 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.
