其典型的显微组织为层片状珠光体。
大量粗片状珠光体的形成与吐丝前后的冷却速度过慢等因素有关。
Formation of large quantities of the flake perlite is closely dependent on the extremely low cooling rate before and after wire-drawing.
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.
次表面为变形的片状珠光体组织，片状碳化物发生碎化，硬度也有一定的提高。
The sub surface were deformed pearlite, the flake carbides were broken, and the hardness increased.
结果表明在相当大的冷却速度范围内，可获得稳定体积百分含量的细片状珠光体加铁素体组织。
The result shows that in a great scope of cooling rates, constant percentage of fine pearlite and ferrite can be obtained.
