初生奥氏体枝晶对高强度灰铸铁力学性能的影响

Effect of primary austenite dendrites on the mechanical properties of high-stregth grey cast iron

灰铸铁初生奥氏体枝晶对机械工程中广泛使用的灰铸铁的性能有着重要的影响。本文概括地介绍了初生奥氏体枝晶与灰铸铁抗拉强度之间的关系,并比较具体地介绍了高强度灰铸铁中的初生奥氏体枝晶的退火金相显示方法。

With concrete metallograph after annealing, the relationship between the dendrites and tensile strength of grey cast iron has been described as the former has an important effect on the later which has been widely used in mechanical engineering.
