摘要：
The effect of base material (BM) on microstructure and crystallographic orientation evolution of a Ti-6Al-4V electron-beam welded joint was investigated. Meanwhile, the crystallographic orientation of prior beta grains was studied by advanced electron backscattered diffraction data processing. The inhomogeneity of microstructure within welded joint was formed due to the different microstructures of BM. By comparing microstructure details of the welded joint, including microstructure morphology and crystallographic orientation with those of the base material, it can be found that both the microstructure morphology and crystallographic orientation of the EBW joint would be controlled by BM.
