Abstract Most currently used rapid solidification techniques (such as melt spinning, melt extraction, melt drag, planar flow casting, double anvil, hammer and anvil and splat quenching) are simple variants on a common theme. Molten metal is brought into contact with a cool substrate, usually metallic. The molten metal forms a bond with the substrate,

Fluctuations in solidification
Physical Review E, 1993We present an analytical treatment of (i) the incorporation of thermal noise in the basic continuum models of solidification, (ii) fluctuations about nonequilibrium steady states, and (iii) the amplification of noise near the onset of morphological instability.

Emergence and Solidification-Fluidisation
2021The Artificial Intelligence (AI) paradigm is based on the mirroring of human Natural Intelligence (NI) into a technical machine concept, with the aim of maximising computability in the von Neumann sequential manner. The goal of this article is to give some key prospects of general and actually foreseen global parameters for some AI-NI properties ...

Langevin formalism for solidification
Physical Review Letters, 1993The question of how thermal noise should be incorporated in the continuum equations of solidification in a way which is consistent with both bulk and interfacial equilibrium fluctuations is investigated. The proper Langevin formalism which accomplishes this task is found to consist of the usual bulk forces, which remain unaffected by the presence of a ...

This chapter is devoted to solidification of binary A-B alloys of nominal solute composition Co. The interpretation of a binary phase diagram depends on the composition of an alloy (Co Ce) and its freezing temperature range \(T_{s}\leq T_{f}^{\ast }\leq T_{l}\), the solidification velocity.
