EFFECTS OF SCANDIUM ON HYPO-EUTECTIC ALUMINUM COPPER MICROSTRUCTURES UNDER LOW SOLIDIFICATION RATE CONDITIONS
Download2017-11-01
Bogno, A.-A., Valloton, J., Henein, H., Ivey, D.G., Locock, A.J., Gallerneault, M.
This work addresses the microstructures and mechanical properties of Al-4.5 wt% Cu alloys containing 0.1, 0.2 and 0.4 wt% Sc that were solidified under low cooling rate conditions (< 1ºC/s) and then heat treated. The samples were solidified in a differential scanning calorimeter before being heat...

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...

Efficient photoinduced charge transfer in chemically-linked organic-metal Ag-P3HT nanocomposites
Download2016-01-01
Feng, Lin, Chen, Ming, Zheng, Fei, Niu, Meng-Si, Zhang, Xuehua, Hao, Xiao-Tao
A novel nanocomposite of P3HT and Ag nanoparticles (Ag-P3HT) has been synthesized by laser ablation. The fluorescence wavelength of the nanocomposite can be tuned by varying the ablation duration. The steady-state emission maximum at 580 nm for pristine P3HT shows significant blueshift to...

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 of Cold-Wire Addition Effect on Heat Input and Productivity of Tandem Submerged Arc Welding for Low-Carbon Microalloyed Steels
Download2016-01-01
Mohammadijoo, M., Ivey, D.G., Collins, L., Henein, H.
The addition of a cold wire in conventional tandem submerged arc welding (TSAW), i.e., the CWTSAW process, is proposed to improve the productivity of pipeline manufacturing by increasing welding travel speed and deposition rate, while retaining adequate joint geometry without increasing the...

Tan, Huanshu, Diddens, Christian, Ly, Pengyu, Lohse, Detlef
Evaporating liquid droplets are omnipresent in nature and technology, such as in inkjet printing, coating, deposition of materials, medical diagnostics, agriculture, the food industry, cosmetics, or spills of liquids. Whereas the evaporation of pure liquids, liquids with dispersed particles, or...
