At last, the density of dislocation of the material increases greatly after hot forging, then segregation of carbon occurs, which also result in non-uniformly austenite and then spheroidal pearlite.

During the study, spheroidal pearlite of spheroidal-graphit cast steel has been achieved after hot-forging or normalizing first.

另外本文在研究过程中，发现在锻造和正火条件下得到了粒状珠光体，这在球墨铸钢领域里是未见报道的。
