Conversion of p–n conduction type by spinodal decomposition in Zn-Sb-Bi phase-change alloys

NPG Asia Materials, 2020
Phase-change films with multiple resistance levels are promising for increasing the storage density in phase-change memory technology. Diffusion-dominated Zn 2 Sb 3 films undergo transitions across three states, from high through intermediate to low ...

Suppressing spinodal decomposition by incorporation of reduced graphene oxide into (Sn0.5Ti0.5)O2 solid solution

Materials Research Express, 2020
Here, it is found that the incorporation of rGO into (Sn _0.5 Ti _0.5 )O _2 solid solution suppresses spinodal decomposition via two characteristic routes.

Comment on “Theory of Spinodal Decomposition” [PDF]

Physical Review Letters, 1996
I comment on a paper by S. B. Goryachev [PRL vol 72, p.1850 (1994)] that presents a theory of non-equilibrium dynamics for scalar systems quenched into an ordered phase. Goryachev incorrectly applies only a global conservation constraint to systems with local conservation laws.

Unexpected spinodal decomposition in as-cast eutectic high entropy alloy Al30Co10Cr30Fe15Ni15

Materials & Design, 2023
By integrating calculation of phase diagram (CALPHAD) simulations, ab initio molecular dynamics (AIMD) and experimental validation, we shed light on the unexpected spinodal decomposition in as-cast Al30Co10Cr30Fe15Ni15 alloy, as opposed to the eutectic ...

Pattern formation mechanisms in sphere-forming diblock copolymer thin films [PDF]

Papers in Physics, 2018
The order-disorder transition of a sphere-forming block copolymer thin film was numerically studied through a Cahn-Hilliard model. Simulations show that the fundamental mechanisms of pattern formation are spinodal decomposition and nucleation and growth.

Formation of lamellar microstructure in Ti-48Al-7Nb-2.5V-1Cr alloy

Materials & Design, 2022
The reasonable design and application of phase transformation is an efficient approach to coordinate the microstructure and properties of alloys. The sequence of compositional and structural transformation determines the type and mechanism of phase ...

Precipitation-site competition in duplex stainless steels: Cu clusters vs spinodal decomposition interfaces as nucleation sites during thermal aging

, 2020
Competing microstructural evolution mechanisms can exist simultaneously when duplex stainless steels are operating for several decades in a high temperature service environment. Such competition between different microstructural evolution pathways can be
