| Abstract: | By analyzing the mechanism of brittleness forming in the EBW joint between rhenium and titanium alloy, the brittleness can be overcome by adding intermediate layer. The elements of intermediate layer are confirmed according to the analyzing result, and several kinds of intermediate layer with different composition are designed.EBW joints without brittleness are finally obtained after welding test. |
