Vacancy Formation Energy in Close-packed Metals Connected with Liquid Thermodynamics at Melting

Abstract

The vacancy formation energy in units of the melting temperature can be approximated for close-packed metals in terms of the difference in specific heats and the long wavelength limit of the liquid structure factor. Here, some results are first presented for d-electron metals to complement earlier data on s-p metals. Secondly, contact is made with the semiempirical treatment of Miedema.

Key Words:

• Vacancies
• hot crystals
• Miedema's model
