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...

Wiskel, J.B., Ma, J., Valloton, J., Ivey, D.G., Henein, H.
Strain aging of microalloyed steel pipe can occur at the relatively low temperatures associated with the pipe coating process and/or during long term storage. A Box-Behnken statistical design is used to determine the significant strain aging variables that affect the longitudinal yield strength...

Bhattacharya, Sujit, Arora, Nitin, Ng, Samson, Chong, Jeng Y., Kresta, Suzanne M., Machado, Marcio B.
Mixing conditions were explored as a possible avenue for improvement of demulsifier performance in solvent diluted bitumen de-watering process. The effects of demulsifier bulk concentration, demulsifier injection concentration and mixing energy on water and solids removal from the oil phase were...

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...

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...

Influence of Cold-Wire Tandem Submerged Arc Welding Parameters on Weld Geometry and Microhardness of Microalloyed Pipeline Steels
Download2016-01-01
Mohammadijoo, M., Henein, H., Collins, L., Ivey, D.G.
Tandem submerged arc welding with an additional cold wire (CWTSAW) is being developed for pipeline manufacturing to improve productivity in terms of deposition rate and travel speed of welding. An appropriate understanding of the welding conditions to guarantee requisite weld geometry, appearance...

Bubble formation from plasmonic heating of nanostructures is of great interest in many applications. In this work, we study experimentally the intrinsic effects of the number of three-dimensional plasmonic nanostructures on the dynamics of microbubbles, largely decoupled from the effects of...
