Preparation of High-Nitrogen Ductile Iron by Injecting Nitrogen Gas in Molten Iron
High-nitrogen ductile iron (DI) was prepared by a new method of injecting nitrogen gas into molten iron and nodularizing treatment. The microstructure and mechanical properties of the as-prepared DI for different nitrogen gas injection periods were characterized. The graphite morphology gradually de...
