Distortions that do not affect the symmetry of the final product phase obtained in a martensitic transition, so-called non-symmetry-breaking order parameters, but that do affect the energy barrier encountered during homogeneous nucleation, are considered. For the bcc-to-9R transition undergone by Na, first-principles total-energy calculations verify the importance of these distortions in that a 40% reduction is obtained when the non-symmetry-breaking order parameters are allowed to alter thedoi:10.1103/physrevb.43.13626 pmid:9997202 fatcat:4gg2cyomnzexrfmvx6hc4uw25y
