现代球墨铸铁是英国人 Morrogh 和 Williams 在1947年首先公开宣布研制成功的,它是现代科学技术的产物,三十年来已成为发展最快,最有前途的铸铁材料。但是,远在 Morrogh 之前两千年,只拥有原始技术手段的中国铸造匠师已曾得到石墨形状符合现代球铁标准的铸铁。这虽然难以想象,却是千真万确的铁铸的事实。本文一系列金相照片所示铸铁组织,如果不加说明,任何一个铸造工作者都会毫不迟疑地
Modern ductile iron was first publicly announced by the British Morrogh and Williams in 1947. It is a product of modern science and technology and has been the fastest growing and most promising cast iron material for three decades. However, only two thousand years before Morrogh, Chinese foundry craftsmen, who had only original technical means, had obtained cast iron with graphite shapes that met the modern ductile iron standard. Although this is unimaginable, it is true and true iron casting fact. This series of metallographic photographs shows the cast iron organization, without explanation, any one of the foundry workers will not hesitate to
