A Study of Rapidly Solidified Al1.5wt%/3wt%Mg0.2wt%Sc Powders and Strips using Impulse Atomization
DownloadFall 2016
In this work, rapid solidification microstructures and mechanical properties of Al1.5Mg0.2Sc and Al3Mg0.2Sc are investigated. Samples in the form of powders and strips / deposits of different thermal histories are obtained by means of impulse atomization technique. Cooling rates of the powders,...

Bottom-up controls of flammability in the Canadian boreal forest at multiple temporal and spatial scales
DownloadFall 2023
Wildfires are the most common disturbances occurring in the Canadian boreal forests. Their incidence and characteristics are controlled by different factors at different temporal and spatial scales. At every scale, vegetation is an essential factor fueling fires. Despite its importance, some...

Bedel, M., Reinhart, G., Bogno, A.-A., Gandin, Ch.-A., Jacomet, S., Boller, E., Nguyen-Thi, H., Henein, H.
The Impulse Atomization process developed at the University of Alberta (Canada) enables metallic powders to be solidified with well controlled process parameters. The inner microstructure of several droplets of Al-4.5wt.%Cu alloy produced by this technique has been investigated by using both...

Design and processing conditions of hypoeutectic Al-Cu-Sc alloys for maximum benefit of scandium
Download2017-01-01
Bogno, A.-A., Henein, H., Gallerneault, M.
Addition of Sc to Al-Cu is reported to be responsible for a high precipitation hardening upon heat treatment and serves as a good grain refiner. However, Scandium is presently very expensive, therefore, getting maximum benefit from a minimum addition would be economically of value. This work...

Bogno, A.-A., Henein, H., Ivey, D.G., Valloton, J., Reinhart, G., Sediako, D., Gallerneault, M.
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...

Estimation of Droplet Size and Temperature at which Solidification starts in a Drop Tube-Impulse System.
Download2016-01-01
Delshad Khatibi, P., Henein, H.
D2 tool steel powders were produced using a drop tube-impulse atomization technique. In order to measure the radiant energy and droplet size of atomized D2 steel droplets, DPV-2000 (Tecnar Automation Ltée, St. Hubert Quebec, Canada) was utilized. In-situ velocity and droplet size of the atomized...
