Nematic-isotropic spinodal decomposition kinetics of rodlike viruses [PDF]
, 2006 We investigate spinodal decomposition kinetics of an initially nematic dispersion of rodlike viruses. Quench experiments are performed from a flow-stabilized homogeneous nematic state at a high shear rate into the two-phase isotropic-nematic coexistence ...

PLA Foaming Process and Its Research Progress
Macromolecular Materials and Engineering, Volume 311, Issue 9, September 2026.Poly(lactic acid) (PLA) foaming is mapped from molecular structure and gas–polymer interactions to extrusion, autoclave, injection, and 3D‐printing routes. The review reveals how crystallization, rheology, pressure history, and flow govern cellular architecture, while highlighting intelligent control, sustainable blowing agents, and multimodal ...

Spinodal Decomposition in Crystal
, 1972 Spinodal decomposition has been studied both theoretically and experimentally in isotropic materials and in cubic crystals by Cahn. Some experimental work and a partial theoretical study of spinodal decomposion has also been made in tetragonal crystals ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT The performance optimization of ultrahigh‐strength Cu‐15Ni‐8Sn alloy relies on controlling recrystallization and aging precipitation, which are two thermally activated processes constrained by high activation barriers. Conventional heat treatment requires elevated temperatures and prolonged holding time, inevitably leading to grain coarsening ...

Asymptotic behaviour of spinodal decomposition
, 1989 We report a numerical study of the asymptotic regime of spinodal decomposition. Specifically, we find (a) that the characteristic pattern size shows a power-law growth with exponent 0.33; and (b) that the effect of noise is asymptotically ...

Materials Research Express, 2015 In quasi binary systems like AgBr–NaBr the demixing from the homogeneous high temperature phase into separated phases is a complex process that depends on the ageing temperature as well as on the quench rate.

Accessing Ultra‐Nano Phase‐Separated Metallic Glasses via Cryogenic Cycling
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Phase separation offers a promising avenue to mitigate the inherent brittleness of metallic glasses. However, traditional approaches relying on mixing enthalpy face significant challenges, primarily due to the detrimental impact on glass‐forming ability.

Effect of dislocations on spinodal decomposition in Fe-Cr alloys
, 2009 Phase-field simulations of spinodal decomposition in Fe-Cr alloys with dislocations were performed by using the Cahn-Hilliard diffusion equation. The stress field of dislocations was calculated in real space via Stroh's formalism, while the composition ...

Frontiers in Materials, 2020 The alloy system Al-(Co)-Cr-Fe-Ni contains compositional ranges where a solid state BCC-FCC phase transformation leads to dual-phase materials composed of face-centered cubic (FCC) and body-centered cubic (BCC) phases with nearly equal volume fraction ...

What is spinodal decomposition?
Journal of Engineering Science and Technology Review, 2008 Abstract: Phase separation may occur in a way that the growth is not in extent but in amplitude. Only in the unstable region such a procedure is thermodynamically feasible. In a phase diagram the unstable region is defined by the spinodal. When a system has crossed this locus, phase separation occurs spontaneously without the presence of a nucleation ...
