摘要
利用光学显微镜、扫描电镜、薄膜透射电镜研究了惯性摩擦焊缝组织的形成。结果表明，焊缝组织沿径向有较大的变化。心部为细小的等轴组织，焊口为片状组织，从心部到焊口形成了Ｖ字形焊缝。
The formation of weld microstructure in inertia friction welding by was studied mans of microscope,SEM and TEM.The results show that microstructure of weld zone greatly changes in the radial direction. The centre of joint is characterized by fine equiaxial grains.The flashing is by lamellar structure.A“V”shape weld zone is formed from the centre of joint to the flashing.
