近年来国外对可锻铸铁石墨化理论、石墨化动力学、热力学开展了新的研究。关于研究孕育处理、热处理的理论与实践方面的报导也很多。对白口铁凝固过程和可锻铸铁的机械、物理性能的研究也十分重视。国外一些公司和研究工作者还对可锻铸铁与球墨铸铁在性能、成本、可靠性、加工性能等多方面进行了分析比较,提出了较全面深入的看法,为正确评价和选用这两种铸铁提供了科学依据。
In recent years, foreign countries on the malleable iron graphitization theory, graphitization kinetics, thermodynamics to carry out a new research. There are also many reports on the theory and practice of inoculation and heat treatment. The research on the white iron solidification process and the mechanical and physical properties of the malleable iron is also very important. Some foreign companies and researchers also made a comparatively comprehensive and in-depth view on the performance, cost, reliability, processing performance and other aspects of malleable iron and ductile iron, and provided a comprehensive and in-depth view for the correct evaluation and selection of these two kinds of cast iron Scientific basis.
