Abstract

Effects of different addition amounts of rare earth (RE) and Si-Ca on inclusions, the microstructure and mechanical properties of Steel 35MnSiCrMoV were investigated by accordingly using optical microscope, scanning electron microscopy with energy dispersive spectrometry, transmission electron microscope, tensile and impact testing machine. The results show that the addition amounts of RE and Si-Ca have significant impacts on the shape, size, distribution and quantity of inclusions, the microstructure and mechanical properties of steel 35MnSiCrMoV. It can make the size of inclusions and the thickness of martensite reduce to nano scale and steel 35MnSiCrMoV obtain high strength, adequate ductility and high impact toughness at the same time through adding 0.3% (wt.%) RE and 0.1% Si-Ca into the steel.
