摘要
本文介绍了高碳当量灰铸铁中奥氏体枝晶的形貌及其对裂纹扩展的阻碍作用,以及化学成分、冷却速度、合金元素、冶金因素等对奥氏体枝晶数量的影响。
The relationships between the amount of austenite dendrite and chemical composition、coolling rate、alloy elements and metallurgical factors of grey cast iron with high carbon equivalent were investigated, and the morphology of austenite dendrite and their effect on resisting crack propagation were also discussed.
