Zw. Wang et al., A simple model for assessing the high pressure melting of metals: nickel, aluminum and platinum, PHYSICA B, 293(3-4), 2001, pp. 408-416
High-pressure melting has been of general interest for our understanding of
solid-liquid phase transition due to the importance in high-pressure physi
cs and material science, and here a simple model was developed to address t
he high-pressure melting of metals. For this simple model, a critical volum
e representative for the melting point is determined compared to the refere
nce volume. Then employing the relation of thermal pressure and temperature
, the melting temperature for solids at high-pressure conditions can be eas
ily obtained. The calculated results for nickel and aluminum and platinum i
ndicate that this model can well reproduce the high-pressure melting of abo
ve metals, in excellent agreement with the existing experimental data. A co
mparison between experimental data and our calculated curves reveals that t
he melting under extreme compression can be better obtained by this simple
model than that by previous empirical melting equations. (C) 2001 Elsevier
