Formation of Quasicrystals and Related Structures in Systems of Aluminum with Transition Metals. II. Binary Systems Formed by Aluminum with 4d and 5d Metals

摘要

Numerous systems for aluminum with transition metals have been found to contain quasiperiodic phases (quasicrystals) having symmetries forbidden by classical crystallography. These phases are metastable in binary systems and have been obtained by rapid cooling from the liquid or gaseous phases. Binary quasicrystals are considered along with revised phase diagrams for the systems Al - 4d-M and Al - 5d-M (M from Mo to Pd and from W to Pt).
