最近二十年来,合金钢中的碳化物受到许多科学工作者的重视和研究,这促进了我们对于现有合金钢的了解,并为发展新钢种提供了有用的数据。 本文综合报导作者在这方面的研究工作的主要结果;首先综述过渡族金属的碳化物及在碳钢回火过程中所生成的铁碳化合物,继之间明在低合金钢中合金元素在渗碳体和铁素体两相中的分配,最后讨论在高合金钢中合金碳化物的生成及其与次生硬化的关系。

In the past eight years the carbide phases present in various alloy steels havebeen studied by a combination of electrolytic extraction, microchemical analysis,X-ray identification, and electron microscopic examination methods, and themain findings are presented here under the following headings: 1. Carbides of transition metals. 2. Iron carbides precipitated during tempering. 3. The partition of alloying elements between cementite and ferrite. 4. The precipitation of alloy carbides and secondary hardening. 5. Carbides in tungsten-chromium tool steels.
