一、低合金铸铁有四篇文章报道了灰铸铁和球墨铸铁合金化的近况。它们对于用各种合金元素来改善组织和性能的可能性作了有益的评述,并指明了他们的优缺点。在题为“工频炉炉料的成分”的文章中,对合金载体及其加入铸铁的有效方法作了很简要的介绍。 First, the low alloy cast iron Four articles reported the status of the gray cast iron and ductile iron alloying. They provide a useful review of the possibilities of using various alloying elements to improve the organization and performance and indicate their strengths and weaknesses. In an article entitled “Composition of Power Frequency Furnace Charges”, a brief description of the alloy carrier and its efficient method of adding cast iron is provided.
