Melting of metals under pressure

Lindemann's formula of melting is extended in terms of bulk modulus and Gruneisen parameter to study the pressure dependence of melting temperature, T-m(P) of metals. The formalism is applied to study T-m(P) of noble and transition metals, di-, tri- and tetravalent (Ag, Au, Cu, Mn, Mg, Zn, CD, In, Pb and Al) metals over a wide range of pressures up to 12 GPa. The computed melting temperatures of the metals under pressure using our semi-empirical relation is in good agreement with the experimental data. (C) 2013 Elsevier BY. All rights reserved.
