worm-shaped

The analysis of the structure and break of the minor diameter cast iron bars shows that developed primary austenite dendrites distribute in framework; With the high-power electron microscope to observe the D-type graphite between dendrites, the graphite is approximately worm-shaped or coral-shaped.

对小直径铸铁型材的组织及断裂行为分析表明：发达的初生奥氏体枝晶呈框架结构分布；枝晶间的D型石墨在高倍电镜下观察石墨的形状近似呈蠕虫状或珊瑚状。
