Structure of the α–β Interface in a PdCu Solid Solution
2020
In accordance with the orientation ratio (110), [001]β || (111), [$$1\bar {1}0$$]α established by fast electron diffraction between the ordered (β) and disordered (α) phases in the foil of a Pd + 57 at % Cu solid solution, the atomic structure of the interface is modeled by molecular dynamics. It is found that the structural and size discrepancies are compensated by interfacial dislocations with Burgers vectors a/2〈111〉 in coordinates of the β-phase.
