The Microstructure of the Membrane Alloy Pd-9.1 at Y

The microstructure of the membrane alloy Pd-9.1 at Y has been studied by X-ray diffraction using synchrotron radiation and transmission electron microscopy with electron diffraction. It has been shown that the matrix phase in the alloy has a face-centered cubic lattice. The presence of Guinier–Preston zones and formation of the ordering of the alloy atoms have been determined. The presence of defects enriched with atoms of the same type has been revealed. The deformation fields they create have been studied.
