Thermodynamic calculation of sulfide and nitride precipitation in high grade non-oriented silicon steel
The equilibrium concentration relationship of precipitates was obtained by thermodynamic calculation of sulfide and nitride of the high grade non-oriented electrical steel 50W350.Below the li-quidus temperature,AlN precipitates in the range of 1 700-1 788 K,TiN in the range of 1 588-1 788 K,MnS in the range of 1 768-1 788 K,Cu2S in the range of 1 420-1 768 K.The existence of precipitates in each temperature range has been confirmed through detection.
