通过对高牌号无取向电工钢50W350硫化物、氮化物的热力学计算,获得了析出物的平衡浓度关系.液相线温度以下,AlN在1 700~1 788 K温度区间析出,TiN的析出温度区间为1 588~1 788 K,MnS的析出温度区间在1 768~1 788K范围内,Cu2S的析出温度范围为1 420~1 768 K,并通过实际检测,证实了各温度区间析出物的存在.
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.
