High-pressure melting curves of FCC metals Ni, Pd and Pt with defects

摘要

The high-pressure melting curves of defective metals Ni, Pd and Pt with face-centered cubic structure have been studied up to 100 GPa by using the statistical moment method. Our melting theory is based on the absolute stability limit for crystalline state. The effects of pressure and vacancies on the melting properties of Ni, Pd and Pt have been considered. These obtained results are consistent with previous experiments and other theoretical calculations.
