摘　　要：在铌微合金高强度钢中,主要利用铌来提高奥氏体的再结晶温度,从而实现控制轧制和控制冷却;同时,利用铌的析出进行强化来提高铌微合金钢的强度和韧性。结合取向硅钢抑制剂的特点和要求,分析了Nb(C,N)作为抑制剂的可行性。由于Nb(C,N)在钢中的固溶温度低,析出颗粒尺寸小,Nb(C,N)具备作为取向硅钢抑制剂的基本特征和优势,故其可作为取向硅钢中抑制剂。In niobium microalloyed high strength steels, niobium can increase the non-recrystallization temperature so that controlled rolling and controlled cooling can be realized. Meantime, niobium precipitation strengthening is utilized to further improve the strength and toughness of the steels. In this paper, the feasibility of Nb（C,N） as inhibitors in oriented silicon steels was analyzed in consideration of the characteristics and requirements of inhibitors. Nb （C,N） can be used as promising inhibitors in oriented silicon steels due to its good features and superiority such as lower solubility temperature and smaller precipitate size, compared with conventional inhibitors.
