用透射电镜研究了Fe-C-Mo 和Fe-C-Si-Mn 合金中温转变早期产物的组织形态,发现在整个中温转变范围非平衡先析型转变都是按贝氏体铁素体相变基元形成及其扩散生长演化方式进行,说明经生长演化一些时间后的基元难于作为判断贝氏体形核机制的形态学依据。从基元生长演化进程区分了低碳贝氏体和板条马氏体。
The structure morphologies of products formed in the earlier stage of inter-mediate transformation in the experimental alloys Fe-C-Mo and Fe-C-Si-Mn have beeninvestigated with TEM.It was found that in whole intermediate temperature range thetransformation
