α ⇆ β phase transformations in rolled foil of the Pd–57 at % Cu solid solution

α ⇆ β phase transformations in rolled foil of the Pd–57 at % Cu solid solution We have studied phase transformations of a 20-μm-thick rolled foil of the Pd–57 at % Cu solid solution in a heating–cooling cycle. The as-prepared foil was two-phase, with a nanocrystalline structure. The mutual orientation of the α- and β-phases corresponded to the Nishiyama–Wassermann orientation relationship. Using X-ray diffraction and resistivity measurements, the β ⇆ α phase transformations were shown to be reversible. The effect of the severely deformed initial structure shows up as a shift in the onset temperature and end point of the α → β phase transformation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Inorganic Materials Springer Journals

Abstract

We have studied phase transformations of a 20-μm-thick rolled foil of the Pd–57 at % Cu solid solution in a heating–cooling cycle. The as-prepared foil was two-phase, with a nanocrystalline structure. The mutual orientation of the α- and β-phases corresponded to the Nishiyama–Wassermann orientation relationship. Using X-ray diffraction and resistivity measurements, the β ⇆ α phase transformations were shown to be reversible. The effect of the severely deformed initial structure shows up as a shift in the onset temperature and end point of the α → β phase transformation.
