Formation of Thin Foil of the Ordered Pd—Cu Solid Solution with a CsCl-Type Lattice during Magnetron Sputtering

摘要

Among Pd-based membrane alloys [1], the Pd—Cu system has long attracted attention for deep hydrogen purification. This system is distinguished by the formation of a CsCl-type ordered solid solution (β phase) [2] in a rather narrow composition range close to Pd— 40 wt%Cu.
