Phase Formation and Stability

2009
Locally similar icosahedral structural ordering between parent phase and nucleating phase is believed to be responsible for the frequently occurring formation of icosahedral quasicrystals from undercooled liquid alloys or during devitrification of metallic glasses.

Diffractive phase elements for pattern formation: phase-encoding geometry considerations

Applied Optics, 1997
Space-invariant, multilevel, diffractive phase elements are designed for large-scale pattern-formation tasks. The importance of the design algorithm and the phase-encoding geometry of the diffractive element is discussed with regard to the performance of both on- and off-axis reconstruction, notably for pixelated gratings.

Theory of phase formation in aqueous two-phase systems

Journal of Chromatography B: Biomedical Sciences and Applications, 1996
Currently there are a number of different mathematical models for phase equilibria in aqueous two-phase systems available. This diversity can create some confusion for model users, since most models seem to perform reasonably well. Choosing a model, thus, becomes rather a difficult task.

Phase formation in A3003 alloys

Materials Today: Proceedings, 2019
Abstract A number of intermetallic compounds can potentially form in the A3003 series of aluminium alloys, such as Al3Fe, Al6Mn, Al2Cu and α-Al15Si2M4, as well as Al9Fe2Si2 and Al8Fe2Si, despite of the low alloying element contents. The phase formation depends on not only the metallurgical history but also the actual alloy composition, as illustrated

Thermodynamic aspects of metastable-phase formation

Philosophical Magazine B, 1990
Abstract The behaviour of thermodynamic properties in metallic liquid glass-forming systems is reviewed. It is shown that they are compatible with the hypothesis of progressive ordering on cooling. Trends for the ideal glass-transition temperature are calculated as a function of composition for different types of phase diagram.

Micelle formation and phase separation

Journal of the American Chemical Society, 1990
Le but de cette communication est de presenter des donnees experimentales afin de proposer une explication sur la relation entre la formation des micelles et le modele de separation des phases. Le cas de la formation des micelles de laurate de potassium dans des micelles de laurate de potassium dans des solutions de KOH est etudie par spectrometrie ...

Phase formation in titanium glazes

Glass and Ceramics, 1997
Phase formation in titanium-containing systems is examined. The results of studies of phase formation under crystallization are reported for the SiO2−TiO2−CaO−Al2O3−B2O3−Na2O system. The principal phases in the compositions studied were found to be sphere, anorthite, and rutile.

Germanide phase formation and texture

2006 International SiGe Technology and Device Meeting, 2006
The aim of the present study was to complete a systematic investigation of metal-germanium reactions to isolate promising candidates for contacting Ge-based microelectronic devices. Based on their low formation temperature, low resistivity, limited film roughness, sufficient morphological stability, and limited sensitivity to oxidation, NiGe and PdGe ...

Laves phase formation in solids

Journal of Materials Science, 1994
Structural changes of the Fe-Mo, Fe-Ti and Fe-Nb binary alloys have been investigated by means of electron microscopy and X-ray diffraction. A tweed structure representing modulation of the composition always precedes the Laves phase precipitation. The latter fact allows confirmation that the Laves phase precipitation proceeds by the spinodal mechanism.
