运用TEM和SEM研究了Fe-13％Mo-0.8％C合金铸态组织的形态和结构。结果表明:Fe-Mo—C合金枝晶芯部δ共析组织很少,而出现一些小共晶;共晶碳化物为骨骼状的M_6C,共析碳化物为棒条状的M_6C。
The structure and morphology of as-cast Fe-13wt-%Mo-0.8wt-%Calloy have been observed under SEM and TEM. Few δ-eutectoid but certain minoreutectic appeared in the core of dendrites of the alloy. The eutectic carbide is foundas skeleton M_6C while the eutectoid carbide as rodlet M_6C.
