Elastic constants of the C49 and C54 phases of TiSi2, thin films have been
measured by surface Brillouin spectroscopy; the results were exploited to e
stimate other thermodynamic parameters such as the melting and Debye temper
atures and surface free energies of both phases. The C49 form displays much
softer elastic parameters than the C54 bulk-stable structure. Furthermore,
the estimated thermodynamic parameters of C49 appear to be lower than thos
e of C54. (C) 2001 Elsevier Science B.V. All rights reserved.
