1) big flake perlite
粗片状珠光体
1.
Results show that large quantities of big flake perlite occurring in the structure of the wire rod is the cause directly to the rupture of the wire rod.
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。
2) lamellar pearlite
片状珠光体
1.
It is a question worth discussion whether lamellar pearlite and sorbite could co-exist in the view field of optical microscopes and whether lamellar pearlite and sorbite could be identified simply via lamellar structures.
在光学显微镜的视场中,片状珠光体与索氏体是否可以共存;同时,是否可以简单地根据是否能够区分层片状结构来划分片状珠光体与索氏体值得探讨。
2.
45 steel row material for cold extrusion performed pre-normalizing can eliminate the widmannstaetten structure,banded structure,and form the uniform lamellar pearlite.
45钢冷挤压零件原材料预先正火,彻底消除魏氏组织、带状组织,形成均匀片状珠光体,然后在球化退火时,才能获得碳化物颗粒均匀、圆整、弥散分布在铁素体基体上的理想组织。
3) fine lamellar pearlite
细片状珠光体
4) Coarse pearlite
粗珠光体
5) lamellar pearlite
层状珠珠光体
6) lamellar pearlite
片层珠光体

It was found that along with UFC temperature drop the diameter of spheroidal pearlites and interval of lamellar pearlites both decrease if the UFC rate is higher than 100 ℃/sec after high-temperature final rolling to cool the workpiece to a certain degree then it is slowly cooled to ambient temperature.
研究发现:高温终轧后以大于100℃/s的冷却速度超快速冷却到一定温度后缓冷到室温,随着超快冷段终冷温度降低,珠光体球团直径和片层间距减小;终冷温度过高只能使晶界碳化物厚度减薄但不能抑制其呈网状析出,降低终冷温度到715℃以下就可以得到抑制了网状碳化物析出的细片层珠光体型组织;随着终冷温度继续降低显微硬度增加并有退化珠光体产生,其显微硬度可达到426 HV。
补充资料:珠光体
奥氏体在A1温度共析分解产生的组织,本质上是一种铁素体和渗碳体相间成层排列的混合物。由于显微镜下图象状似珠母,被称为pearlite,译名珠光体。珠光体是钢中最常见的组织之一。珠光体一词又常用于描述冶金学中所有其他成层排列的共析组织(见铁碳平衡图)。
