Peculiarities of Polymorphic Transformation in Titanium

The regularities of the α ↔ β polymorphic transformation in VT 1-00 polycrystalline titanium are investigated using differential scanning calorimetry. The activation energies of the α → β transformation upon titanium heating (760 ± 30 and 1100 ± 100 kJ/mol) are determined and are found to be depende...

Description
Summary:The regularities of the α ↔ β polymorphic transformation in VT 1-00 polycrystalline titanium are investigated using differential scanning calorimetry. The activation energies of the α → β transformation upon titanium heating (760 ± 30 and 1100 ± 100 kJ/mol) are determined and are found to be dependent on the thermal previous history of the metal. It is proposed that the transformation mechanisms during heating and cooling are controlled by nondiffusive and diffusive mechanisms realized in overlapping temperature intervals.
