Long-period superstructures in Cu_3±xPd

Fine scale investigation of some phenomena in metallic alloys by field ion microscopy and atom probe microanalysis

“…Such a behaviour strongly suggests a two-step evolution of the demixing kinetics. As recently reported [20], the appearance of these high Cr-peaks may be connected with the existence of long-range Cr- [26,27]. Various topologies may also be observed according to the chemical composition or the temperature of ordering.…”

“…Various topologies may also be observed according to the chemical composition or the temperature of ordering. APB's can be straight or wavy and spread over a few atomic planes [27,28] and the value of the mean size of ordered domains (M) may be commensurate or incommensurate with the lattice parameter (a).…”

Cu3Pd Observed by High-Voltage Electron Microscopy

“…The dashed lines are ordering spinodals, to be discussed later. The two open circles shown on the diagram indicate the presence of one-dimensional LPS according to BRODDIN et al [11]. Clearly, in that region, the one-dimensional LPS may well be metastable with respect to the two-dimensional LPS, and both one-and two-dimensional LPS are cenainly metastable with respect to the stable ~ + W equilibrium.…”

“…ordering analog of the ANNNI model. A reasonable model for Cu-Pd, however, would likely require terms beyond n = 2 [11,15].…”

Bimetallic PdCu and PdCu3Particles Prepared by Wet Impregnation-HRTEM Study of the Structure and the Interface with the MgO Substrate

“…The variations in the periodicity was studied by high resolution electron microscopy as a function of composition and temperature of annealing [7].…”
