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...

Downhole tools made of dissolvable alloys (DAs) are getting more attractive, especially with the difficulties that arise from drilling wellbores with longer lateral distances. To date, most of the DAs are based on Al alloys (AAs) or Mg alloys, which offer undesirable mechanical properties. This...

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...

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...
