1)  ramiform carbide
枝状碳化物
2)  spheroidal carbide
球状碳化物

对GCr15钢进行不同的热处理工艺试验,以获得不同级别的网状碳化物,网状碳化物对冲击性能的影响研究表明:网状碳化物级别升高,冲击性能下降;还研究了退火态与淬回火态网状碳化物之间的关系。
2.
The influences of accelerated cooling technology after rolling on pearlite and network carbide were studied.
研究了GCr15轴承钢棒材轧后水冷对所析出的珠光体形态和网状碳化物级别的影响,结果表明:在其他工艺参数相同的情况下,随着轧后冷却时间的延长,珠光体球团直径和片层间距减小,网状碳化物级别降低,水冷后返红温度为715℃时,可以得到细小的珠光体和少量弥散分布的碳化物,返红温度在715℃以下,随着温度继续降低对组织影响不大。
3.

2.
A technology combining ultra-fast cooling with slow cooling after high temperature finishing rolling was created against the serious precipitation of carbide network.
针对国内某钢厂连轧生产线上出现的网状碳化物严重析出问题,提出高温终轧后超快速冷却与缓冷相配合技术,在精轧机后安装超快速冷却器,对60 mm棒材高温终轧后超快速冷却到一定温度后缓冷,从而抑制了网状碳化物的析出,使过冷奥氏体完全发生伪共析转变而得到细片层间距的珠光体型组织-索氏体,并促进珠光体形核减小珠光体球团直径,减小C原子扩散能力细化了珠光体片层间距,得到了利于球化退火的理想组织。
6)  sheet carbide
