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...

Wiskel, J.B., Ma, J., Ivey, D.G., Henein, H.
Transverse tensile samples were extracted from the centreline position of three different compositions of uncoated thick walled microalloyed X70 UOE pipe at a location 180° from the weld. Aging heat treatments of 5, 15, and 25 minutes and temperatures of 175, 215, and 255°C were applied. Tensile...

Hoque, Md. S., Saha, A., Chung, H., Dolez, P. I.
Fire-protective fabrics made from high-performance fibers are available to provide protection from various hazardous conditions such as extreme heat and flame. However, these fabrics are often exposed to other deteriorating conditions, including moisture. It is a concern for the user's safety as...

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...

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...

Herlach, D.M., Burggraf, S., Reinartz, M., Galenko, P.K., Rettenmayr, M., Gandin, Ch.-A., Henein, H., Mullis, A., Ilbagi, A., Valloton, J.
The dendrite growth velocity in Al75Ni25 melts has been measured in a containerless procedure as a function of undercooling using an electromagnetic levitation technique both in the Earth laboratory and in Space on board the International Space Station. The growth shows an anomalous behavior...
