This is in accordance to the argument that the phase separation for Ml, M2, and M3 is by spinodal decomposition and hence, very fast leading to an asymmetric structure.
We speculate the formation of Pd-rich and Cu-rich phases by spinodal decomposition. Given that both phases were segregated from the same B2 structure, the two alloy phases may coexist in each nanoparticle or may have separated into isolated nanoparticles.
Besides, in our opinion, such a behavior could also be caused by spinodal decomposition of these solid solutions [21-24].
With increasing Al content of the alloy, the volume fraction of interdendrite gradually decreases and a net-like structure formed by spinodal decomposition is observed in dendrites, especially at x [greater than or equal to] 1.0.
Its physical applications have been extended to many areas of scientific fields such as spinodal decomposition [1,3], diblock copolymer [4-6], image inpainting [7], multiphase fluid flows [8-10], microstructures with elastic inhomogeneity [11, 12], tumor growth simulation [13,14], and topology optimization [15, 16].
However it is important to note that the alphaalph[alpha]' spinodal decomposition occurring in the ironchromium-based ferrite is responsible for this aging susceptibility.
The selection of blends with near critical composition guarantees the phase separation following spinodal decomposition (SD) mechanism, and thus the whole process could be well characterized by TRLS.
The alkali borosilicate material is formed using a proprietary process that involves phase separation via spinodal decomposition, which causes the borate-rich phase to orient from the outside to the inside of the shell and then leach out.
Built with an alkali borosilicate, the composition is phase-separated via spinodal decomposition. The borate-rich phase is oriented from the outside to the inside of the shell, then leached out, leaving behind an interconnected porosity on the scale of 100 to 1,000 A.
Among the topics are spinodal decomposition versus nucleation and growth, using the lattice Boltzmann algorithm, to explore phase ordering in fluids, aging in domain growth, morphological transitions in microphase-separated diblock copolymers, and the dynamics of phase transitions in solids.
The organized pattern is similar to the so-called bicontinuous spinodal decomposition structures, which are usually found during the phase separation in the systems of multi-components.
