摘要：

The lattice dynamics, third–order elastic (TOE) constants and thermal expansion of h.c.p. hafnium are worked out employing a model based on Keatmg'e approach. The lattice heat capacity of hafnium calculated using a frequency distribution function that involves 50 880 frequencies, shows reasonably good agreement with the experimental data. The variation of the lattice parameters of hafnium is also investigated using its TOE constants in Thurston's extrapolation formulae. © 1979 Taylor & Francis Group, LLC.
