Abstract
Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis are used to study the structure, phase composition, and deformation behavior of a titanium Ti–10V–2Fe–3Al alloy with different carbon contents. It is shown that as the carbon content in the alloy increases to the maximum carbon solubility, the dispersity of the secondary α-phase increases and, therefore, the strength of the alloy increases. After reaching the carbon solubility limit, titanium carbide particles are observed in the alloy structure; the morphology of the particles and their sizes are similar to those of the primary α-phase. The titanium carbide particles do not affect the strength and plasticity characteristics of the alloy during tensile tests and retain their initial shape after deformation. At the stage of strain localization, titanium carbide particles are sites of micropore nucleation.
