The formation of dispersive distribution of fine cementite particles could be explained by the mechanism of dissolution-re-precipitation.

细小渗碳体粒子在铁素体基体上的弥散分布可以用溶解－再析出机制来解释。

A lamellar mixture of cementite and ferrite formed during the cooling of austenite; a micro-constituent of steel and cast iron.

在奥氏体冷却的过程中形成的碳素体和铁素体的层状混合物，是钢和铸铁的微量成分。

Because alloy cast iron is made of 15 ~ 25% cementite,5 - 10% pellet~shaped graphite, pearlitic matrix.

这是因为合金铸铁的材质是由？5-25％渗碳体、5—10％球状石墨、珠光体基体所组成。

It is generally considered that the simple mechanical mixture of ferrite and cementite is gained in the pearlite transformation and there is prevenient phase in this process.

一般认为，珠光体转变得到铁素体和渗碳体的机械混合物，而且存在领先相。

The redistribution of cementite particles in the ferrite matrix has been observerd, which can be interpreted in terms of dissolution-reprecipitation mechanism.

渗碳体粒子在铁素体基体上的弥散分布可以用溶解－再析出机制来解释。
