1) Al-containing cementite
含铝渗碳体
1.
The morphology of Al-containing cementite,owing to its instability,changes rapidly from grain-boundary-network or pearlite lamella to fine dispersed particles during heating afterwards,giving excellent high temperature plasticity and hot-workability to the steel.
由于这种含铝渗碳体的不稳定性,在随后的加热中会迅速由喷射态的晶界网络形态或珠光体片层状转化为分散而细小的颗粒,从而使该材料具有很好的高温塑性和热加工性能。

含Ni渗碳钢
补充资料:渗碳体
即碳化铁Fe3C,一般含碳6.67%,是一种具有极高硬度(BHN600以上)的脆性化合物。呈斜方结构。渗碳体的数量、形态和分布对钢和铸铁的性能影响很大。渗碳体是碳在退火和正火钢中以及白口铸铁中的一般存在形式,也是共析组织珠光体的组成之一(另一为铁素体)。在过共析钢中,则作为自由渗碳体,在珠光体晶界呈网状析出,或以片状在晶内析出。当淬火碳钢的回火温度超过约250℃时,马氏体中的过饱和碳以针状或片状渗碳体的形态析出。渗碳体内经常固溶有其他元素。在碳钢中,一部分铁为锰所置换;在合金钢中为铬、钨、钼等元素所置换,形成合金渗碳体。渗碳体不是稳定的碳化物,在长时间退火后将最终分解出自由碳(石墨)。
