The annealing of titanium in inert gas, oxygen, vacuum and other
Titanium — metal of silver-white color, has a density of 4.5 g/cm3, a melting point of 1725 °C. To relieve internal stresses after sheet metal forming, titanium parts are subjected to annealing (t° 550−620°C). To release work hardening the semi-finished annealed (t°650−750°C).
The annealing of the first kind
Include normalizing, annealing deregistration is applicable for α-alloys, β-alloys with thermodynamically stable β-phase. In the pseudo-α-alloys, typical of α+β and β alloys with thermodynamically unstable β-phase recrystallization processes may overlap with phase transformation.
The value of the phase transformations in the formation of the metal structure is greatest with deregistration recrystallization and annealing and the lowest during the annealing to remove residual stresses. If the temperature of the annealing for reduction of residual stress is sufficiently low, the phase transformation might not evolve and does not affect the structure and properties of pseudo-α, α+β and β alloys (from thermodynamically unstable β-phase).
It is carried out with the aim of removing the stress after plastic deformation. After this treatment, the full hard metal ezuprechnaya significantly reduced average dislocation density.
In heat-treatable alloys, in particular in β-alloys, polygonization develops in the temperature decay of meta-stable β-phase. In cases when the deformation temperature and cooling rate after deformation was high enough in the deformed semi-finished products. fixed thermodynamically unstable β-phase. When heated, the deformed semi-finished products up to 500−700°C they occur not only the process of return and of polygonization, but the collapse of the metastable β-phase. Properties of the annealed titanium alloys significantly depend on what happens before — polygonization or collapse of the β-phase.
