Ordering kinetics in long-range ordered Cu3Au

Deformation-induced structural transformation in boron-doped Ni76Al24

“…It has been found that in Cu 3 Au [39] and Cu 3 Pt [40], the activation energy of the ordering process is fitted well with the activation energy for the migration of vacancy. It has been shown that DO 22 structure can change to L1 2 structure by simple changes in the location of atoms; so, this is a preferential ordering mechanism, which changes in order in DO 22 to that in L1 2 and because of changes in order, the structural symmetry changes from DO 22 to L1 2 .…”

The radiation-induced order-disorder transformation in Cu3Au

“…The vacancy motion energy was taken from the Cu,Au literature (Feder, Mooney and Nowick 1958, Dugdale 1956, Takamura and Okuda 1973 to lie in the range 0.8-1.1 eV. The energy of motion for an ordering jump was chosen to be slightly larger than Em.…”

Search for an anisotropic Debye–Waller factor in cubic copper-base solid solutions

“…The heat treatments intended to produce enhanced short-range order in the alloys were selected by reference to an X-ray scattering study on aluminium bronze (Davies & Cahn, 1962) and to lattice-parameter measurements on brass (Feder et al, 1958). Detail~ are given in Tables 2-4.…”
