Abstract

Abstract

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 liquidus 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.
- non-oriented silicon steel,
