| Abstract: | The test process of linear friction welding of GH4169 superalloy was discussed.The microstructures and the relations between bonding rate and bending and fracture strength were analyzed.The results show that the bending strength of linear friction welded joint of GH4169 is proportional to the bonding rate and the fracture is tough fracture.The friction duration has a great influnce on fracture strength. |
