Nucleation and the Properties of Undercooled Melts

Nucleation and the Properties of Undercooled Melts

Description:

Nucleation is a central topic in Materials Science because it initiates most phase transformations. When a new phase appears within an existing phase, seeds must form before growth can occur within the given volume. The study of nucleation treats the very early stages, which involve only a limited number of atoms or molecules. It is a branch of fundamental research which has far-reaching implications for processes where nucleation is of paramount relevance to phase and microstructure selection. The development of any new material or processing route always leads to renewed interest in the topic.

Review from Ringgold Inc., ProtoView: The study of nucleation refers to the early stages of materials phase transformations in which a limited number of atoms or molecules are involved in the formation of seeds as a new phase originates from a matrix. Battezzati and Castellero (both: chemistry, U. of Torino, Italy) describe the theory of nucleation and discuss the thermophysical properties which mostly influence its rate. Although the material mostly focuses on classical theory starting from heterophase fluctuations, other theories are also described. Also included is a detailed analysis of quantities related to solidification.
