Singh, AK and Mohan, M and Divakar, C (1982) The kinetics of pressure-induced alpha-omega transformation in Ti. Journal of Applied Physics, 53 . pp. 1221-1223. ISSN 0021-8979Full text not available from this repository.
The kinetics of the high-pressure transformation of the alpha (hcp) phase of titanium to the hexagonal omega phase is measured as a function of pressure with a view towards predicting the kinetics under very high pressures. Changes in electrical resistance were used to monitor the extent of the alpha-omega transformation as a function of time at specimen pressures between 6 and 9 GPa. The time dependence of the fractional omega phase concentration is found to obey an exponential law characteristic of a nucleation and growth process. The pressure dependence of the transformation rate implies that the transformation should occur under shock loading conditions at a pressure of 19 GPa, in contrast to experimentally observed values of 35 GPa.
