Abstract

The invention relates to plastic working of metals and alloys, in particular to plastic working of hypereutectoid alloys based on titanium aluminides η-TiAl (superstructure Ll0-η phase) and Ti3Al (superstructure DO19-α2 phase) produced by casting. Said invention can be used for industrially producing billets, semifinished products and articles made of said materials having a specified structure. The inventive method for said alloys consists in heating and deforming a billet, the deformation of a billet being carried out in two stages. In the first stage, the deformation is carried out within a range of Te Te + ΔT °C, where Te is a temperature of eutectoid transformation, ΔT being selected according to a condition of maintaining the globular constituent of the structure obtained as result of deformation during post-deformation cooling. The deformation rate ε'1 and the degree of strain ε1 are selected in such a way that they reduce the mean dimension of grains/colonies in the billet. In the second stage, the deformation of a billet is carried out under isothermal conditions within a temperature range of Tmin Te °C, where Tmin is a maximum temperature ensuring non-destructive deformation at the degree of strain ε2 and the deformation rate ε 2 which are selected according to a condition of refining the grain dimension η and α2 particles.
