摘要	In order to provide guidance for the regulation of mechanical properties of TC18 titanium alloy built by electron beam wire deposition (EBWD), the fracture mechanism of the alloy has been investigated. The EBWD TC18 alloy exhibits columnar -grains growing opposite to the heat flow. The microstructure is composed of basket weave microstructures and grain boundary -phases. The rupture of EBWD TC18 alloy originates at the grain boundary and is prone to propagate along the grain boundary -phases, leading to decrease in elongation of the alloy. The fracture property of the EBWD TC18 alloy is mainly ductile fracture, which is broken by both normal stress and shear stress. The fracture mechanism is a mixture of intergranular-ductile fracture and transgranular-dimple fracture.
