| Abstract: | Dilatometry measurements and single-pass compression experiments on both Mn-Nb-Mo and Mn-Nb-Mo-B high grade pipeline steels were performed by MMS 200 thermomechanical simulator.CCT diagrams for the tested steels were determined,and the effect of boron on microstructures with different cooling rates and dynamic recrystallization were investigated.The results show that: the transformation range of lower bainite is enlarged and the start temperature of bainite transformation is lowered by addition of boron.At ... |
