In the diffraction patterns, strong intensity changes are found that provide evidence for a structural phase transformation that is significantly different from the alpha-alpha'-Pd-H bulk phase transition. The structural transition is reversible and driven by the hydrogen concentration. The intensity changes are consistent with a cubic-to-icosahedral structural phase transition obtained in molecular dynamical simulations using embedded-atom-method potentials. | | Comment of the Author/Creator: | Date: 2002, JUN | | External Publication Status: | published | | Document Type: | Article |
