Quantification of Dendritic and Eutectic Nucleation Undercooling in Rapidly Solidified Hypo-Eutectic Al-Cu Droplets
Download2016-01-01
Bogno, A.-A., Delshad Khatibi, P., Henein, H., Gandin, Ch.-A.
This paper reports on the quantification of primary dendritic and eutectic nucleation undercoolings during rapid solidification of impulse atomized hypo-eutectic Al-Cu droplets. The procedure consists in determining the eutectic fraction of each investigated droplet from the fraction of...

Bogno, A.-A., Hearn, W., Spinelli, J.E., Valloton, J., Henein, H.
This paper reports on the development of Solidification Continuous Cooling Transformation diagrams that relate the solidification paths to the inherent microstructures of binary and ternary alloys. The methodology is based on the quantification of a solidified microstructure for its various phase...

Binyaminov, Hikmat, Elliott, Janet A. W.
The effects of a dissolved gas on the behavior of liquid in cylindrical nanopores are investigated in the framework of Gibbsian composite system thermodynamics and classical nucleation theory. An equation is derived relating the phase equilibrium of a mixture of a subcritical solvent and a...

Near eutectic Al-Cu droplets were rapidly solidified by Impulse Atomization. A wide range of microstructural scales was obtained at different cooling rates and undercoolings. The micrographs of the investigated samples revealed two distinct zones of different structural morphologies: An undulated...

This paper reports on the undercooling and growth morphology of Al-4.5wt%Cu and Al-4.5wt%Cu-0.4wt%Sc with a focus on the effect of Sc addition. It is found that the addition of Sc reduces the undercoolings of both primary phase and eutectic. In addition, the morphology of the Al-4.5wt%Cu-0.4wt%Sc...
