Study of Melting Temperature of Metals: Pressure Dependence

Abstract

The melting temperature of metals are studied using the statistical moment method, going the quasi-harmonic appromations. The melting temperature of metals are calculated as a function of the pressure. We discuss the pressure dependence of melting temperatures of Ce, Fe metals and compare the present results with those of the experimental results.

Application of the statistical moment method to melting properties of ternary alloys with FCC structure

“…By following this path, it is easy to consider the effects of pressure and impurities on the melting properties of the crystals without heavy computation workloads. Theoretical results performed by the SMM approach have agreed well with experiments in many systems [18,19]. However, in previous studies, authors have only applied the SMM method to predict the melting of metals and binary alloys [17][18][19].…”

“…For metals, authors in Ref. [17,18] assumed that T m ≈ T S and the assumption provides a good agreement between SMM calculations and experimental data. When applying the SMM approach to the melting of binary alloys while assuming that T m ≈ T S , the theoretical predictions exhibit a significant deviation from experiments [21].…”
