Grain boundary (GB) phase transitions can change drastically the properties of polycrystals. The GB wetting phase transition can occur in the two-phase area of the bulk phase diagram where the liquid (L) and solid (S) phases are in equlibrium. The GB wetting tie line appears in the L+S...

The terms GB phase13 or complexion11,12,14 have been introduced as analogs to bulk phases to underline that these interface phases can only exist in contact to other bulk phases. Each GB phase is characterized by distinct thermodynamic excess properties9,10,15, which can have an impact on, ...
the green curves on the plot show the lowest GB energy calculated versus the atomic fraction of the corresponding grain boundary plane. The blue triangles at the origin of the plot correspond to the Kite structures obtained by theγ-surface approach that does not add or remove atoms. The plot...
DM Anderson,GB Mcfadden,AA Wheeler - 《Annu.rev.fluid Mech》 被引量: 1724发表: 2003年 Lattice Boltzmann simulations of liquid-gas and binary fluid systems We present the details of a lattice Boltzmann approach to phase separation in nonideal one- and two-component fluids. The collision rules ...
Further improvements in efficiencies with sub-fJ (0.9 fJ/bit) modulation were obtained using a compact microdisk with R=2.4 μm radius, exhibiting simultaneously 25 Gb/second modulation, and low-voltage operation of 0.5 V. To achieve this result, a highly optimized vertical p-n junction [83]...
Recent calculations have shown that grain boundary (GB) stress is too small to stabilize finite GB facets, suggesting that the existing theory of GB deface... Istvan Daruka,JC Hamilton - 《Physical Review Letters》 被引量: 13发表: 2004年 鎢(111)表面上的皺/平相變之研究; Faceting and deface...

Single-shot GBCT simulation The performance of the proposed method is first demonstrated on numerical simulations. The simulated phantom exhibits X-ray attenuation, refraction, and ultra-small-angle scattering. To create this phantom the FORBILD head phantom18 was extended to three sub-phantoms with...
