Investigation of the Mechanism of Precipitation of the (2)-phase in a Two-Phase Titanium - Aluminum Alloy

摘要

We study the processes of formation of an ordered Ti3Al phase ((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 -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 -region.
