| Abstract: | As the substrate for nucleation of primary austenite in welding metal, the effectiveness of rare earths inclusions and the most common inclusions such as Al 2O 3, SiO 2 and MnO in medium high carbon steel during surfacing were analyzed and calculated in detail. The calculation according to the theory of planar lattice disregistry shows that as the heterogeneous nuclei of primary austenite in medium high carbon steel during surfacing, the Ce 2O 3, La 2O 3 and Ce 2O 2S are effective, and the SiO 2, Al 2O 3, MnO and CeS are ineffective. |
