摘要
QTNi35Si5Cr2的基体组织是奥氏体+石墨+铬的复合碳化物,本文通过高温下缓慢冷却和快速冷却得到了不同的常温力学性能。通过对比分析确定了最佳QTNi35Si5Cr2的热处理工艺,并把这一结果编入《高镍奥氏体铸铁件》国家标准。
The matrix of high nickel austenite ductile iron is composed of austenite, graphite and chromium compound carbides. This article analyzes the different mechanical properties at room temperature obtained by slow cooling and rapid cooling under high temperature. After comparison analysis, the best heat treatment process for the high nickel austenite ductile iron was determined. This result is incorporated in GB standard of high nickel austenite cast iron.
