Fracture characteristics of titanium alloy samples obtained by electron beam additive manufacturing
In this work, the fracture features of a titanium alloy Ti-6Al-4V samples obtained using the electron beam wire-feed additive manufacturing have been investigated. Studies have shown that the main character of sample fracture is viscous, with an in-grained dimple rupture observed. The strongest samples are characterized by the absence of defects in the fracture structure. For some samples, there are pores with sufficiently large sizes. Sample tests show a low dependence of mechanical properties on the direction of the applied load. Mechanical properties of the whole series of samples vary within the range of 3 – 6 %.In this work, the fracture features of a titanium alloy Ti-6Al-4V samples obtained using the electron beam wire-feed additive manufacturing have been investigated.
