Investigation of the Mechanism of Precipitation of the α2-phase in a Two-Phase Titanium – Aluminum Alloy

We study the processes of formation of an ordered Ti 3 Al phase (α 2 -phase) in Ti – Al alloys depending on the modes of heat treatment. It is shown that the high-temperature treatment performed in the single-phase α-region followed by supercooling at different temperatures leads to a more active pr...

Description
Summary:We study the processes of formation of an ordered Ti 3 Al phase (α 2 -phase) in Ti – Al alloys depending on the modes of heat treatment. It is shown that the high-temperature treatment performed in the single-phase α-region followed by supercooling at different temperatures leads to a more active precipitation and the growth of dispersed particles than the preliminary treatment in the β-region.
