1.球墨铸铁贝氏体区的等温转变——K. Rohrjg《HTM》,39,1984,2,41～49[德文]经贝氏体转变的球墨铸铁,具有特别有用的强度、耐磨性和韧性的综合性能,其性能是以铁素体、奥氏体和马氏体构成的细晶粒基体组织为基础的。本文论述了球墨铸铁的组织结构、性能和热处理条件——相变温度、转变时间、奥氏体化温度、合金成分——两者之间的关系,以及它的实际应用。并介绍了这种新材料的应用实例。 2.在饱和与平衡渗碳过程中的渗层增长——J. Wunning,《HTM》,39,1984,2,50～54[德文]近年来,由于要求大幅度地节约时间,出现了一种新的渗碳方法。因而,采用电子计算机通过影响最大的系统偏差,研究了渗碳过程的动力学。在饱和渗碳过程中,渗层增长最快,而对温度的变化
1. Isothermal Transformation of Ductile Iron in Ductile Iron - K. Rohrjg “HTM”, 39, 1984, 2, 41-49 [German] The bainitic cast iron has a particularly useful strength, The combined properties of strength and toughness are based on the fine grain matrix structure of ferrite, austenite and martensite. This article discusses the structure, properties and heat treatment conditions of ductile cast iron - phase transition temperature, transformation time, austenitizing temperature, alloy composition - the relationship between the two, and its practical application. And introduced the application of this new material examples. 2. Seepage Growth During Saturation and Balanced Carburizing - J. Wunning, “HTM”, 39, 1984, 2, 50-54 [German] In recent years, due to the requirement of significant time savings, A new carburizing method. Therefore, the kinetics of the carburization process has been studied by using an electronic computer to influence the maximum system deviation. In the saturated carburizing process, the infiltration layer grows fastest, while the temperature changes
