摘自《机械工程材料》1984年第2期,羊秋林的文章: 本文是一篇综述文章,作者就高铬铸铁的成分、特性及其影响因素,以及它在冶金、机械设备上的应用进行了概述。高铬铸铁成分为了获得良好性能,满足使用要求,作者认为关键是控制马氏体或奥氏体(或混合组织)基体组织及铬的特殊碳化物。为此,应控制C和Cr含最,当Cr<12％或>30％将对抗磨性都不利,C量过高达到过共晶成分时对抗磨性也不利,此外,Cr、C含量对奥氏体的稳定性具有决定性作用,适当地控制C/Cr比,可作为奥氏体的稳
Excerpt from “Mechanical Engineering Materials” No. 2 of 1984, Yang Qiu Lin’s article: This article is a review article, the author on the composition, characteristics of high-chromium cast iron and its influencing factors, and its application in metallurgy, machinery and equipment Outlined. High Chromium Cast Iron Components In order to achieve good performance and meet the requirements of use, the author believes that the key is to control the martensite or austenite (or mixed tissue) matrix and the special chromium carbide. To this end, C and Cr should be controlled with the most, when Cr <12% or> 30% will be unfavorable to the anti-wear, C content is too high to the eutectic composition of the anti-wear is also unfavorable, in addition, Cr, C content The stability of austenite has a decisive role, appropriate control of C / Cr ratio, can be used as austenite stable
