Titanium and Its Alloys


  1. 1.

    The diffusion coefficient in α-titanium at the transformation temperature is by about two orders greater, while the activation energy is half of that in β-titanium. A qualitatively similar rule holds for technically pure titanium although the diffusional mobility in it is less and the activation energy greater than in iodide titanium.

  2. 2.

    The difference between diffusion parameters in α and β-titanium can be related either to the different strength of the interatomic bonds or to structural peculiarities of α-titanium.

  3. 3.

    Structural changes in titanium during diffusion annealing result in an accelerated self-diffusion.
