【摘要】 本文对12Cr2MoWVTiB钢正火处理试样进行了薄膜透射电镜观察,测定出无碳贝氏体中(M-A)相的精细结构及其晶体几何学取向关系;并依据(A-A)相的结构特征,对其相变机制作了某些探讨。更多还原

【Abstract】 Thin foil of normalized specimen of 12Cr2MoWVTiB steel has been examinedby TEM. The fine structure and crystallographic orientation relationship of the(M-A) phase in carbonless bainite were determined. In the light of the observedstructure features the transformation mechanism of (M-A) phase was also discussed.更多还原
