The rate of solidification affects the microstructure, quality and mechanical properties of the castings. The analysis of heat transfer in centrifugal casting is very complex due to rapid solidification, rotating mould, opaque mould and high temperature. As the grain size is directly depending on the rate of solidification of the casting, based on grain size the rate of solidification of the ce...

Numerous experimental data on the rapid solidification of binary systems exhibit the formation of metastable solid phases with initial (nominal) chemical composition. This fact is explained by complete solute trapping leading to diffusionless (chemically partitionless) solidification at a finite growth velocity of crystals. Special attention is paid to developing a model of rapid solidification...

Kinetic phase diagrams in technical alloys at different solidification velocities during rapid solidification are of great importance for guiding the novel alloy preparation, but are usually absent due to extreme difficulty in performing experimental measurements. In this paper, a phase-field model with finite interface dissipation was employed to construct kinetic phase diagrams in the ternary...

A thorough understanding of crystallization kinetics for rapid polymer solidification during the fiber spinning process is a route to maximizing fiber properties while increasing production speeds. We are using theoretical, computational, and experimental models to characterize the crystallization process at the molecular, microscopic, and macroscopic levels. Polymer dependent molecular descrip...

The directional solidification of the transparent binary alloy succinonitrile-poly(ethylene oxide) was studied in an experiment in which solidification speeds of about 2 mm/sec could be reached without loss of the linear temperature gradient. The low diffusivity of the polymer solute allowed the study of the dynamics of rapid solidification using an optical microscope. For both normal and doubl...
