An in situ electron microscope study of precipitation in palladium-hydrogen alloys
E Ho, HA Goldberg, GC Weatherly, FD Manchester - Acta Metallurgica, 1979 - Elsevier
Thin foils of annealed high purity Pd have been loaded with H to the approximate
compositions PdH 0.05, PdH 0.3 and PdH 0.6 and allowed to transform at room temperature
and liquid N 2 temperature. At room temperature only incoherent dendritic precipitation is
observed. At liquid N 2 temperatures both coherent and incoherent precipitation is observed
and a transformation from coherent to incoherent plates by dislocation nucleation within the
particles is found. In a dispersion of coherent and incoherent precipitates, the metastable …
