摘要
利用透射电镜技术,对钢102,即12Cr2MoWVTiB低合金耐热钢焊接接头各特征区组织的精细结构变化进行了观察。初步讨论了组织变化对焊接接头机械性能的影响。
The microstructural alteration of 12Cr2MoWVTiB heat resisting steel welded joint is observed with the transmission electron microscope(TEM) techniques. The effect of the structural alteration on the mechanical properties of the welded joint is discussed preliminarily.
