摘　　要：选择适当的化学成分,用铜和钼配合进行合金化,采取一定的工艺手段,可以获得铸态贝氏体球铁,其基体组织主要由羽状贝氏体和残留奥氏体构成,具有良好的综合力学性能。目前已在减速机齿轮中得到应用。The as-cast bainite ductile iron can be produced by selecting proper chemical composition of molten iron and proper process way and alloying with Cu and Mo. The as-cast bainite ductile iron have good mechanical properties. The matrix structure is most composed of feathery bainite and remained austenite. Now it has applied to driven gears. It'll bring remarkablely social benifit.
