Abstract：The bright ghost structure often appears in the macrostructure of TC4 titanium alloy. It can cause the failure of space vehicle. This paper analyzes the fracture appearance, microscopic structure, chemical composition and micro-hardness of the bright ghost structure. It proves that the essence of the bright ghost structure is the composition segregration of raw and processed material. This article describes the forming reason of the bright ghost structure and the preventing methods.
