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...

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...

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 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...

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...
