Abstract
Electron beam was used to join TC4 alloy to Ti3Al-based alloy. The composition of the weld was analysed by XRD and TEM and the results showed that the weld mainly composed of α′ martensites. The change of heat input had little influence on the composition of the weld but can make the grain size increasing. The fracture path of the joints was mainly decided by the microstructure of the weld and started from coarse grain zone to HAZ and base metal of Ti3Al alloy.
