蠕虫状石墨铸铁,简称蠕墨铸铁。是一种新兴的工程材料。其石墨形态介于球状与片状之间,是一种过渡型石墨。在国外也有叫致密石墨、聚集片状石墨、厚片状石墨及珊瑚状石墨等多种名称。 1.蠕虫状石墨的类型 蠕虫状石墨是一种复杂的空间相连枝状聚集体。它的聚合度介于灰铁与球铁之间,其长度l与厚度d之比一般为2～10,比片状石墨(l/d>50)小得 Worm-like graphite cast iron, referred to as compacted graphite iron. Is a new engineering materials. The graphite morphology between spherical and flaky, is a transitional graphite. In foreign countries also called dense graphite, aggregate flake graphite, flaky graphite and coral graphite and other names. 1. Worm-like graphite type Worm-like graphite is a complex space-linked dendritic aggregates. Its degree of polymerization is between gray iron and ductile iron, its length l and thickness d ratio is generally 2 to 10, smaller than the flake graphite (l / d> 50)
