Abstract:
The microstructure, phase composition, and parameters of the $\alpha$-Ti based solid solution in the Ti–6Al–4V alloy obtained by 3D printing without cooling and with water cooling of the titanium substrate were studied by the methods of X-ray diffraction analysis, transmission diffraction and scanning electron microscopy, and optical metallography. It was found that the use of water cooling of the substrate leads to a decrease of the hereditary $\beta$ grains sizes, an increase in the volume fraction of the $\beta$-phase, a decrease in the volume fraction of the $\alpha''$-phase and the total mean square displacement of atoms in the $\alpha$-Ti crystal lattice, as well as an increase in the elastic macrostrain of the samples.
Keywords:
additive technologies, microstructure, phase composition, total mean square displacements of atoms, X-ray diffraction analysis, transmission diffraction and scanning electron microscopy.
