Rapid solidification of Al-Cu droplets of near eutectic composition

Michel Rappaz, Jonas Valloton

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 differ ...

Numerical Model of Rapidly Solidified Droplets of Al-33 Wt Pct Cu Eutectic Growth

Michel Rappaz, Jonas Valloton

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 regu ...

Modeling of peritectic coupled growth in Cu-Sn alloys

Michel Rappaz, Jonas Valloton, Jonathan Dantzig

In directional solidification experiments on hypoperitectic Cu-Sn alloys at low velocity and high thermal gradient, both lamellar and fibrous coupled peritectic growth patterns have been observed. Two phenomena that had not been observed in previous experi ...
