摘要：
The omega phase transformation kinetics of TB-13 titanium alloy has been analyzed by non-isothermal dilatometry. The average value of local activation energy determined is about 91.7 kJ/mol. The nucleation and growth mechanism of the omega phase has been investigated by the non-isothermal local Avrami exponent. Both the local Avrami exponent and the local activation energy during the omega phase transformation process change significantly with the transformed volume fraction, indicating that the omega phase transformation mechanism in this alloy varies at different stages. The local Avrami exponent lies between 1 and 2 in a wide transformed volume fraction range of 0.17-0.95, indicating that the dominating mechanism of omega phase transformation in TB-13 titanium alloy is the three-dimensional growth with a near-zero nucleation rate.
