一般地，片状珠光体的强度高于粒状珠光体、塑性低于球状珠光体。
In general, the strength of carbon steel containing lamellar pearlite is higher than that of carbon steel containing nodular pearlite, but the ductility of the former is lower than that of latter.
粒状珠光体的硬度和冲击韧性均优于层片状珠光体，但耐磨性逊于后者。
Both hardness and impact toughness of the granular pearlite are better than that of lamellar pearlite, but the latter has a better wear resistance.
RE偏聚使珠光体转变的开始温度降低，从而减小珠光体的片层厚度及层间距，并导致粒状珠光体的形成。
The C-RE segregation lowers the transformation temperature of pearlite, which lessens the thickness of lamellas and lamellar spacing of pearlite and induces the granular pearlite.
