Isothermal Decomposition of β-Solid Solution in Titanium Alloy Ti – 10 V – 2Fe – 3Al

  • Published:
Metal Science and Heat Treatment Aims and scope

Regular features of variation of structure, phase composition and hardness characteristics in a β-phase-based titanium alloy Ti – 10 V – 2Fe – 3Al subjected to isothermal treatment in a melt of lead and tin for 5 sec – 32 h at 250 – 800 °C after a hold at 860 °C are considered. The types of the phases precipitated in the process of isothermal decomposition of the high-temperature β-solid solution and the dependences of the lattice constant of the β-phase and of the hardness on the temperature-and-time mode of the treatment are determined. Adiagram of isothermal decomposition of the β-solid solution in alloy Ti – 10 V – 2Fe – 3Al is plotted.
