This paper investigates FeCo-based alloy glass formability by high undercooling and high cooling rate solidification technique and the hardness evaluation of the generated samples. For this investigation, Impulse Atomization was used to generate {(Fe60Co40)75B20Si5}96Nb4 powders of different...

This paper reports on the characterization of rapidly solidified Al-4.5 wt% Cu-xSc (x= 0.1, 0.2 or 0.4 wt %). The effect of micro-additions of Sc (up to 0.4 wt %) was examined through microstructural analysis of rapidly solidified, as well as aged samples, by means of electron microscopy, x-ray...

Rapid solidification of D2 tool steel is investigated experimentally using ElectroMagnetic Levitation (EML) under terrestrial and reduced gravity conditions and Impulse Atomization (IA), a drop tube type of apparatus. IA produces powders 300 to 1400 μm in size. This allows the investigation of a...

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...
