我们要讨论的是球化剂不足或球化衰退时(国外有人说这二者有区别)形成的蠕虫石墨,过去称之为厚片状石墨或紧密石墨(图4—1)。珊瑚形石墨则是尚未发展到蠕虫石墨的一种过渡形态(图4—2)。还有一种状如大毛虫的石墨(图4—3),有人也称之为蠕虫石墨,这种石墨未长丰满时就是松枝形石墨

We are going to discuss the worm-shaped graphite formed by the lack of nodularizer or spheroidisation (some people say there are differences between the two), which used to be called thick flake graphite or compact graphite (Figure 4-1). Coral graphite is a form of transition that has not yet developed into worm graphite (Figure 4-2). There is also a shape such as large caterpillars of graphite (Figure 4-3), some people also call worm graphite, this is not long plump graphite is loose when the shape of graphite
