Abstract
The microstructure of composite derived from amorphous Zr65Pd35 alloy and its hydrogen treatment behavior were examined. XRD, SEM and Raman spectroscopy revealed that the composite containing ZrO2, metallic Pd and PdO was formed by heat treatment of amorphous alloy. The Zr65Pd35 alloy heated at 280 °C in air, followed by heat treatment in hydrogen, changed to the composite in which Pd precipitates with less than 100 nm in diameter were embedded in ZrO2 matrix. The unique property of rapid hydrogen absorb and release in a composite derived from alloy was found.
