中文摘要：

评述了基本合金元素（Si、Al、Mn）、微合金元素（Sn、Sb、B、Nb）以及稀土元素对硅钢性能的影响。硅含量的增高,可提高磁感应强度和电阻率;微合金元素锡和锑易在晶界偏聚,使硅钢最终退火组织中{111}〈uvw〉面织构组分减小,{100}面织构组分增加,提高其磁感应强度,降低硅钢铁损;Nb形成的Nb（C,N）析出物,能够抑制奥氏体再结晶,阻碍晶粒长大,从而提高硅钢的强度、塑性;稀土元素可细化晶粒,改善组织性能的不均匀性。Zr、Cr等元素产生钉扎效应,增加了磁滞损耗,降低磁性能。

英文摘要：

The effects of basic alloy elements （Si, Al, Mn）, micro-alloy elements （Sn, Sb, B, Nb） and rare earth elements on the properties of silicon steel were reviewed. The increase of silicon content can ameliorate the magnetic induction strength and resistivity of the steel. The micro-alloy elements of Sn and Sb segregate at grain boundaries easily, it might decrease the {111}〈uvw〉 surface texture component and increase the {100} surface texture component in annealed structure of silicon steel, so as to increase the magnetic flux density and decrease the iron loss of the steel. Nb （C, N） precipitates can inhibit the recrystallization of austenite, and hamper the grain growth, so as to improve the strength and plasticity of silicon steel. RE can refine grain and improve the uniformity of microstructure and properties. The element Zr and Cr can produce pinning effect, so as to increase the hysteresis loss and reduce the magnetic properties.
