碳氮化物析出相有弥散析出、相间析出、纤维状析出及等温转变温度较低时，碳氮化物在铁素体晶内沿位错处弥散析出等形态。

It has been found that interphase precipitation, fibrous precipitation, precipitation on dislocation, precipitation from supersaturated ferrite at lower isothermal transformed temperature.

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。

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.
