Fine crystalline structure of microcrystalline alloys

Assessment of the Fe–Ni–Al system

“…8, gives an idea of the scattering of the data on this part of the diagram, mainly with respect to the g 0 -Ni 3 Al (L1 2 )/ g-Ni þ g 0 -Ni 3 Al (L1 2 ) phase boundary. In particular, the data of Goman'kov et al [70] is in marked disagreement with those of the other authors. The EPMA results of Jia et al [72] seem to be those with greater agreement between each other.…”

“…Vertical section of the FeeNieAl phase diagram from Ni 3 Al to FeNi 3[16,60,67,69,70,72]. The data points are shown to indicate the level of uncertainty on this part of the phase diagram.…”

Antiphase Boundary Defects in Strontium‐Doped Lanthanum Scandate

“…Thus, the location, shape, and nature of the contrast change indicate that the observed defects are likely π type (antiphase) boundaries. [34][35][36][37][38] The presence of the described defects is a consequence of the ordering of atoms in the crystal lattice and some misorientation of the grain areas that occurs when an ordered and disordered state is formed within one grain, which is when LaScO 3 is doped by strontium atoms. This is also proven by the superstructural forbidden reflexes in the microelectron diffraction patterns of various orientations, one of which is given in Table 4.…”

Abnormal behavior of the atomic order parameter during quenching of the Ni3(Mn,V) alloys from the liquid state

“…In addition, the method of transmission electron microscopy with an accelerating voltage of 120 kV was used. The long-range order parameters S were calculated for the Ni 3 (Mn,V) three-component system in the quasi-binary approximation using the standard formula [3] and γ′-phase ratios I 100 /I 200 and I 110 /I 220 . In this case, mutual replacement of Mn and V atoms in the crystal lattice with the L1 2 superlattice was assumed whereas the Ni 3 (Mn,V) stoichiometry remained unchanged [4].…”
