摘要
低碳球墨铸铁经过900℃奥氏体化,在370℃等温适当时间,空冷到室温后可以获得约84%簇条状铁素体和约16%的残留奥氏体组织。该低碳球墨铸铁具有良好的综合力学性能。
The microstructure of 84% acicular ferrite and 16% retained austenite in the low carbon modular cast iron was obtained by austenitizing at 900°C and austempering at 3701 for proper time then air cooling to room temperature. The nodular cast iron possesses comprehensive mechanical properties.
