The temperature dependence of the Debye temperatures of nine face-centred and nine body-centred cubic elements have been calculated from previous elastic-constant measurements. The results have been used to derive the anharmonic pair potential of each element by means of a nearest-neighbour central force theory. A new criterion for melting is proposed, and its results for the above-mentioned materials are seen to be in excellent agreement with experimental values.
