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,...

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...

Effect of Heat Exchanger Volume and Geometry on Power Output of a Low Temperature Difference Stirling Engine
DownloadFall 2022
This work presents the results of an investigation into heat exchanger design for low temperature difference Stirling engines (LTDSEs). The aim of this study was to determine if there is an optimum heat exchanger geometry for producing maximum power output for a LTDSE. There are multiple factors...

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...

Evaluation and Analysis of the Erosion Performance of Flame Spray-Coated Polyurethane Liners
DownloadFall 2016
Polyurethane has excellent wear resistance and is an effective protective liner against erosion caused by the impact of solid particles. However, similar to most polymeric materials, polyurethane has low thermal and electrical conductivity, and this limits its applicability for use in...
