On annealing at 600°C, the disordered body-centered-cubic structure transforms into a CsCl-type ordered structure before practically any of the stable σ phase is formed. The increasing stability of the CsCl-type ordered structure from CrFe to VFe to TiFe indicates that the A-B bond ...
However, it appears that RuSi having the CsCl-type structure will be the thermodynamically most stable phase for pressures greater than 3.6GPa. Fitting of the calculated internal energy versus volume to a fourth-order logarithmic equation of state led to values (at T = 0K) for the bulk ...
vacancies (crystal)/ A6170B Interstitials and vacanciesThe equilibrium distribution of vacancies in an L2 0 superlattice (CsCl-structure) has been discussed recently by several authors employing the Bragg-Williams (B-W) approximation for long-range order (LRO). For small vacancy concentrations the ...
The Landau theory of symmetry and phase transitions is applied to the CsCl-type structure to determine the symmetry-allowed second-order phase transitions at the k = 0 and k = ( a + b) 2 special points. Two distortions of CsCl-type that have been found experimentally, to the rhombohedral...
An ordered structure, which was found in a decagonal quasicrystal with 0.4 nm periodicity in a conventionally solidified Al70Ni20Ru10 alloy, has been examined theoretically by the projection of an ordered body-centred (CsCl-type) hypercubic lattice. The ordered structure can be characterized as ...
The staggered six-vertex model describes the competition between surface roughening and reconstruction in (100) facets of CsCl-type crystals. Its phase diagram does not have the expected generic structure, due to the presence of a fully packed loop-gas line. We prove that the reconstruction and ...
The structure of Y 2Co 3Al 9 was determined by the single-crystal diffraction method (lambda(Mo Kalpha)=0.71073 Aring, mu=19.931 mm -1, F(000)=1104, T=293 K, omega R=0.037 for 555 unique reflections). This new aluminide has an orthorhombic structure of Y 2Co 3Ga 9 type, oS56, ...

In nodal point-type topological materials, their surface states exhibit a Fermi arc type structure. Unlike the topological elements of this class of materials, the surface states of the TNLS should be DHL-type. To confirm the existence of these particular nontrivial topological, i.e., DHL, su...
The structure is related to that of the mineral hematophanite by removing the central PbFeO3 layer; it is also related to that of layered cuprate YBaCuFeO5 by replacing the Y single layer with a Pb2Cl layer.关键词: crystal structures electrochemistry carbon monoxide dehydrogenase nickel ...
