A miscibility gap is a region in a phase diagram for a mixture of components where the mixture exists as two or more phases – any region of composition of mixtures where the constituents are not completely miscible. ... Thermodynamically, miscibility gaps indicate a maximum (e.g. of Gibbs energy) in the composition range.

What causes miscibility gaps?

2.3.

The formation of a miscibility gap (the so-called Nishizawa horn) between the paramagnetic β' (fcc) phase and the ferromagnetic β (fcc) phase is completely caused from the magnetic transition.

What is miscibility gap alloy?

The miscibility gap alloys are thermal storage materials which address many of the current thermal storage issues primarily through the use of metallic components. Metallic PCMs inherently provide the option for high melting point materials with excellent thermal conductivities and energy densities.
