摘　　要：采用透射电镜等试验方法，观察了两种温度１３８０℃及１３１０℃铸坯加热处理的高磁感取向硅钢（Ｈｉ－Ｂ钢）中抑制剂质点（硫化物＋ＡｌＮ）的析出形态，证实较低温度（１３１０℃）处理时对硫化物的析出形态影响小，却促使ＡｌＮ析出更加细小、弥散，因此，提高了抑制剂质点对初次再结晶晶粒长大的抑制效果。By means of TEM observations, the precipitating morphology of inhibitor par-ticles ( sulfide and AIN ) were examined in high - induction grain - oriented silicon steels (Hi - B steel) in which slab heating temperature were at normal 1380 18 and lower l310C . lt was proved that the lowering of slab heating temperature bad a little in0uence on precipitating morphology of sulfide, but improved the dispersed precipitation of AIN. There- fore, inhibiting ability of the inhibitors was strengthened to suppress the growth of primary recrystallization grains in Hi - B steels .
