Abstract

Demixing in a solid-soluted Co-40 at. % Pd alloy has been induced by microwave plasma hydrogen irradiation on mixture of Pd-Co island grains on Si substrate. The microstructure observation and X-ray microanalysis by a transmission electron microscope before and after the microwave plasma hydrogen irradiation provide a clear evidence of demixing in metallic Co-Pd alloys, that may indicate a possibility of the decomposition into Pd hydride and Co under a hydrogen irradiation at high temperatures.
