| Resumo: | Title screen This paper presents the results of an in situ study on the evolution of the microstructure and phase composition of 3D-printed Ti-6Al-4V samples under tension in the transmission electron microscope column. The microstructure of Ti-6Al-4V specimens manufactured by wire-feed electron beam additive technology is shown to consist of columnar primary β-grains inside of which are α/α'-Ti laths separated by layers of the residual β-phase and gathered into packets. A characteristic feature of 3D-printed Ti-6Al-4V samples is the concentration nonuniformity of the alloying elements due to the partial decomposition of the martensitic α'-phase. The reorientation of the α/α'-Ti lattice near interfaces takes place during uniaxial tension. Deformation-induced α'→α" transformations can develop in the reoriented regions of the α/α'-Ti lattice, in places enriched in vanadium. Режим доступа: по договору с организацией-держателем ресурса |
