  • Study on the modification of inclusions by Ca

    2019-8-14 · The effect of Ca treatment on the modification of inclusions in Al-killed GCr18Mo bearing steel was studied and a thermodynamic and kinetic model was established. The experimental results showed that oxygen content in the steel could be reduced from 120 μg/g to the range 5.5–21.6 μg/g by Al-Ca complex deoxidization at 1 873 K.

  • Effect of austempering on microstructure and

    The effect of Mg and Ca treatment on the modification of inclusions in GCr18Mo bearing steel at 1873K was studied by thermodynamic calculations. The stability phase diagrams among Mg, Ca, Al, and O were investigated to understand the fundamentals about the formation of inclusions. The calculated results showed that: (1) Both the alumina and spinel can be modified to MgO …
