钢的机械性能可以通过与Si合金化而显著改善。然而，双相钢中的Si阻碍了热浸镀锌和锌合金化中的合金反应;具体来说，在500°C下经过25 s的锌合金化后，含0.44wt% Si的钢上没有连续的Fe-Zn合金层。这种延迟可能是由于富Si熔融Zn层，其中Si来自于Si氧化物的铝热还原和从钢基体的溶解。
The mechanical properties of steels can be significantly improved by alloying with Si. However, Si in dual phase steel retarded the alloy reaction in hot-dip galvanizing and galvannealing; specifically, a continuous Fe–Zn alloy layer was absent on the steel containing 0.44 wt% Si after 25 s of galvannealing at 500°C. This retardation may be due to the Si-rich molten Zn layer, in which the Si resulted from the aluminothermic reduction of Si oxide and the dissolution from the steel substrate.
