Abstract: The present research status of the second phase such as MnS, AIN and Cu2S is summarized. The types of the second phase in oriented silicon steel and its selection conditions are introduced. The mechanism of the inhibition of the second phase particles and the effect mechanism of Ostwald coarsening on second phase particles are described. The influence of phase particles on magnetic susceptibility and iron loss of different second relative orientation silicon steels is summarized. It is proposed that the combination of short-flow process and low-solution temperature second phase will be the first choice for producing high-end products.

摘要: 总结了MnS、AlN和Cu2S等第二相的研究现状,介绍了取向硅钢中第二相的种类及其选用条件,阐述了第二相粒子发挥抑制作用的机制和Ostwald粗化对第二相粒子的影响,概述了不同第二相对取向硅钢磁感和铁损的影响,提出了短流程工艺与低固溶温度第二相的结合将是生产高端产品的首选。
