Abstract

The results of orthorhombic alloy VTI-4 research are given. To clarify the alloy position on the Ti–Al–Nb state diagram, it is suggested to perform a calculation of the β-stabilizing elements contribution relative to the niobium. The microstructure change was studied as a function of quenching temperatures corresponding to different phase regions. The dependence of the material hardness on the structure-phase state was studied. It was found that a decrease in the quenching temperature leads to an increase in the hardness values, which is due to the release of the ordered O-phase and a decrease in the volume fraction of the plastic β-phase.

Keywords
