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...

Quantification of Dendritic and Eutectic Nucleation Undercooling in Rapidly Solidified Hypo-Eutectic Al-Cu Droplets
Download2016-01-01
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...
