摘要：

This letter shows that the displacive phase transformation from the h.c.p. alpha-phase to the hexagonal omega-phase can be triggered in titanium targets in an unusual way during swift heavy ion irradiations(dagger). This unexpected result is a consequence of the high level of energy deposition in electronic excitation. A model based on the Coulomb explosion mechanism can account for such a phase transformation.
