灰铸铁中不同类型的奥氏体枝晶在材料断裂过程中具有不同行为。控制生产工艺条件，获得发达等轴枝晶组织，是提高灰铸铁强度性能的重要技术措施之一。
Different types of austenite dendrites in gray cast iron behave differently in the fracture process. Controlling the production process conditions and obtaining the developed equiaxed dendritic structure is one of the important technical measures to improve the strength performance of the gray cast iron.
