About the Topic:

Many binary systems exhibit miscibility gaps in the liquid state. It is well known that melts which are passing a miscility gap on cooling, solidify to a regulus consisting of two layers. Such metallic solid bodies are not interesting for technical applications and have also scarcely been investigated scientifically. Genuine interest in demixing systems only arose as it seemed possible to prevent layer formation under zero gravity. However, experiments in space have shown that even under micro-g conditions, phase separation is occurring, but, in a different way as on earth and also not finely dispersed. Afterwards, there resulted an intensive disclosure of the thermodynamics and the kinetics of the separation of liquid immiscible phases. After the discussion of the results obtained, it is indicated how layer formation can be prevented and a finely dispersed structure can be realized in order to enable technical use.
