摘　　要：概述了国内外关于薄壁球墨铸铁件的最新研究进展,介绍了薄壁球墨铸铁件生产与普通球墨铸铁件的区别;论述了各类石墨化和反石墨化元素对组织和力学性能的影响;介绍了真空处理对薄壁球铁件性能的影响,同时介绍了薄壁球铁件力学性能的评价方法。分析当前薄壁球铁研究特点,展望了研究的发展趋势。The recent research development of the thin-wall ductile iron production was reviewed. The differences of fabrication methods between the thin-wall ductile iron production and the ordinary one were emphasized. The influences of the elements with effect of graphitization and anti-graphitization on the microstructures and mechanical properties were discussed. The method for evaluating the mechanical properties of the thin-wall ductile iron production was introduced. The present research directions and the future research trends were discussed.
