The PdPtH system: Phase transformations at high pressure and superconductivity

Studies on crystal structure and superconducting properties of hydrogen solid solutions in the PdPt alloys with 2.8, 10, 15, 25, 40, and 60 at% Pt are presented. Palladium alloying with platinum is shown to decrease the maximum values of superconducting transition temperature attainable at hydrogen...

Beschreibung
Zusammenfassung:	Studies on crystal structure and superconducting properties of hydrogen solid solutions in the PdPt alloys with 2.8, 10, 15, 25, 40, and 60 at% Pt are presented. Palladium alloying with platinum is shown to decrease the maximum values of superconducting transition temperature attainable at hydrogenation. The phenomenon of dissolution to phases rich and poor in platinum is revealed for the solutions based on the alloys containing 15 to 60 at% Pt. Hydrogenation of the samples is performed at hydrogen pressures to 6.5 GPa and temperatures to 350 °C. [Russian Text Ignored].
