In the case of increasing possibility of application Al alloys the Al5.0Mg0.2Sc alloy with 3.0 and 6.0 Li (wt %) after atomisation process was proposed in this study. To characterise liquid alloys the discharge crucible method was used, which allow to determine density, surface tension and...

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...

This paper studies the solidification of hypoeutectic Al–Mg–Sc powders and spray deposited (SD) strips, generated by Impulse Atomization. The effects of Mg content in hypoeutectic Al–Mg–Sc was examined with respect to the extended solid solubility of Mg and Sc in α–Al, microstructure refinement...

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...

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...

The Microstructure, Morphology and Mechanical Properties of Rapidly Solidified Al-10wt%Si Alloy
DownloadSpring 2018
Hypoeutectic Al-Si alloys are widely used in both the automotive and aerospace industries, due to their strong corrosion resistance, good castability and relatively high strength-to-weight ratio. Despite this wide use, these alloys have a major limitation related to the Si phase that forms...
