Valloton, J., Bogno, A.-A., Rappaz, M., Henein, H.
Rapid solidification of Al-Cu droplets of eutectic composition was carried out using Impulse Atomization (a type of drop tube). Two distinct morphologies were observed: an irregular undulated eutectic assumed to form during recalescence, followed by a regular lamellar eutectic. The volume...

Scandium (Sc) is an expensive alloying element which has an important effect on the properties of aluminum alloys. It is of interest to determine for a variety of solidification conditions the effect of minor addition, in the hypoeutectic levels, of Sc on Al alloys. This study builds on past work...

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...

Champdoizeau, Q., Valloton, J., Henein, H.
A hypoeutectic Al–22.5 wt pctCu sample was processed using the Electro-Magnetic Levitator on board of the International Space Station within the frame of the European Space Agency projects NEQUISOL and THERMOLAB. In total, 21 cycles of melting and cooling were carried out, with the last cycle...
