Technical characteristics

Titanium is a silvery-white metal with a density of 4.5 g/cm3 and a melting point of 1725 °C. To remove internal stresses, after sheet stamping, titanium parts are annealed (t° 550-620°C). To remove build-up semi-finished products are annealed (t ° 650-750 ° C).

Annealing of the first kind

Includes recrystallization, precrystallization annealing is applicable for α-alloys and β-alloys with thermodynamically stable β-phase. In pseudo-α-alloys, typical α+β- and β-alloys with thermodynamically unstable β-phase the recrystallization processes may be superimposed on phase transformation.

Phase transformation

The importance of phase transformations in the formation of metal structure is greatest during recrystallization and precrystallization annealing and lowest during annealing to reduce residual stresses. If the annealing temperature for reduction of residual stresses is low enough, the phase transformations may not develop and have no effect on the structure and properties of pseudo-α, α+β- and β-alloys (with thermodynamically unstable β-phase).

Pre-crystallization annealing

It is carried out to relieve stress after plastic deformation. After such treatment the annealed metal becomes softened, the average dislocation density decreases significantly.

Temperature regime

In thermally hardenable alloys, particularly in β-alloys, polygonization develops at the temperature of decay of the meta-stable β-phase. When the deformation temperature and cooling rates after deformation were sufficiently high, the thermodynamically unstable β-phase is fixed in the deformed semi-finished products. When the deformed semi-finished products are heated to 500-700°C, not only the processes of return and polygonization, but also the decomposition of the metastable β-phase occur in them. The properties of annealed titanium alloys considerably depend on whether polygonization or β-phase decomposition occurs earlier.
