摘要: A thin layer of magnetite is sometimes observed in the scales hot-rolled sheets and wire rod at scale-metal interface. The results this study show that produced, during cooling products, by wustite decomposition. time/temperature field which it appears has been defined. This inner composed pure magnetite, epitaxy with neighboring wustite, metal surface not essential to its nucleation. proeutectoīd reaction which, cooling, produces an increase oxygen concentration contact favors subsequent growth layer.
