In range of 860-950 ℃ normalizing, ideal spheroidal pearlite can be achieved after normalizing.

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.

热加工时，位错密度大大增加，使碳出现偏聚，增加了奥氏体不均匀的程度，促进粒状珠光体的形成。
