Characteristics of Deposition Precipitation Process in Production of High Strength and Low Carbon Steel in FTSR

Abstract:

Precipitation characteristics of second phase in HSLC steel produced by FTSR technology have been researched by TEM and EDS in this article. And preliminary research of precipitation conditions of second phase particles in thermodynamics and dynamics have been took. The results indicate that: there’re second phase particles precipitated dispersively in hot rolled HSLC steels by FTSR technology. These particles mainly contain particles of Al₂O₃、MnS and AlN. Thermo dynamical analysis declares that most of the Al₂O₃ and all of the MnS、 AlN particles are precipitated in solid state. That’s why the precipitation process is slowed down by the diffusion velocity of the elements in solid, and thinner particles are precipitated while the material is in solid state than in liquid state.
