Simple metal and binary alloy phases based on the hcp structure: Electronic origin of distortions and superlattices

Abstract: Abstract. Crystal structures of simple metals and binary alloy phases based on the closepacked hexagonal (hcp) structure are analyzed within the model of Fermi sphereBrillouin zone interactions to understand distortions and superlattices. Examination of the Brillouin-Jones configuration in relation to the nearly-free electron Fermi sphere for several representative phases reveals significance of the electron energy contribution to the phase stability. This approach may be useful for understanding high pressure… Show more

“…Along with these basic metallic structures there are phases Cu5Zn8-cI52 and CuZn3-hP3 that are related to bcc through superlattices, distortions and vacancies. In our previous papers we have considered metallic phases based on the bcc and hcp structures [4,5]. Recently we have considered intermediate phases in the Au -Cd alloy system that is isoelectronic to the Cu-Zn alloy system [6].…”

“…It is interesting to consider chemical and physical factors that lead to the formation of complex and distorted phases-derivatives from these structures. Previously, we have considered simple metal structures based on bcc and hcp [4,5] demonstrating the valence electron concentration as a defining factor of structural stability.…”
