| Abstract: | The effect of combined microalloying using a little Mo and microalloying element V, B,Re has been investigated on the mechanical properties of low carbon high strength SiMn3 type bainitic steel. The results show that combined microalloying can remarkably improve the mechanical properties of the steel, such as as-air cooled toughness, low temperature toughness, temper resistance and strength after high temperature tempering. |
