A low-temperature X-ray diffraction study of Pd and some Pd-H alloys

摘要: The lattice parameter of Pd has been measured between room temperature and 6K found to be a smooth function over this range. An investigation the X-ray diffraction patterns some beta phase Pd-H alloys mixed ( alpha + ) alloy their dependence on cooling through 50K region, where anomalies in number physical properties -phase are known occur, showed no discernible effect state strain lattice, i.e., indication homogeneous excess 2.5*10-5, nor evidence line broadening indicative inhomogeneous strains. Some consequences result for mechanisms which have suggested account these considered.
