Similarly, the overheated solid will undergo a transition, where the lattice softens, as the structure cannot support vibrations with larger and larger amplitudes.S (l-s), the entropy difference between liquid and solid, andG (l-s), the Gibbs energy difference between liquid and solid, cross ...
Transitions between solid and liquid phases were investigated to estimate the melting temperature of the clusters. Although the melting temperatures showed non-monotonic behaviour as a function of cluster size, their general tendency follows the classical relationship Tm n1/3 to the cluster size n. ...
Differential thermal analysis in hydrostatic apparatus yielded for K2CO3: solid-liquid transition (905 ± 2°C intercept at 1 bar), 20.2 ± 0.6 deg kbar1 slope and solid-solid (421 ± 2°C), 16.8 ± 0.8 deg kbar1, to 5 kbar; Na2CO3: solid-solid (485 ± 3°C), 15.5 ± 0.5 ...

The low temperature range of fusion, in mixtures with a very high difference of melting points between pure compounds, also evidence that solid–liquid transition did not present a common behavior. Some other observation that corroborates with the singularity of the solid–liquid transition in this...
The internal friction of the Pb-Sn alloys was measured during heating process fr om room temperature to high temperature.It is reported that there is a sudden dr op in the internal friction curves of the vibration systems with the presence of solid-liquid transition of the Pb-Sn alloys.The ...
