早在1959年Доршек,С.И.等就做了加磷于含硅1.8％的硅钢以改善性能的试验,证实磷促使合金晶粒长大的能力比硅大四倍,且降低附加损耗,但至今未证实已在工业上得到应用。Foley.T.F.等对许多铁基二元及多元合金的磁性基本参数,如电阻率、饱和磁感、磁晶各向异性和磁致伸缩等作了较系统的研究,认为磷的作用与硅近似,但显著降低塑性。
As early as 1959, Доршек, С.И., Et al. Did experiments on the performance of silicon steel with silicon 1.8% silicon added to improve the performance. It was confirmed that phosphorous promoted the growth of alloy grains four times larger than silicon and reduced the additional loss. But so far it has not been confirmed that it has been applied industrially. Foley.TF and many other iron-based binary and multi-alloy magnetic basic parameters such as resistivity, saturation magnetization, magnetocrystalline anisotropy and magnetostriction were made more systematic study that the role of phosphorus and silicon approximation , But significantly reduces ductility.
