Hearn, W., Bogno, A.-A., Spinelli, J.E., Valloton, J., Henein, H.
Hypo-eutectic Al-Si alloys are widely used in both the automotive and aerospace industries, however, they still have limited usage as structural materials, due to the inherent morphology of the Si phase that forms within the eutectic structure. This non-ideal Si morphology can be modified, via...

Bogno, A.-A., Hearn, W., Spinelli, J.E., Valloton, J., Henein, H.
This paper reports on the development of Solidification Continuous Cooling Transformation diagrams that relate the solidification paths to the inherent microstructures of binary and ternary alloys. The methodology is based on the quantification of a solidified microstructure for its various phase...

Wiskel, J.B., Linchieh, A., Henein, H.
A series of infrared temperature videos were taken of the upper surface of hot rolled microalloyed steel skelp immediately following laminar cooling. In addition to validation of the skelp temperature and skelp cooling patterns, local temperature minimums were observed in the infrared images....

Bogno, A.-A., Valloton, J., Jimenez, D.D., Rappaz, M., Henein, H.
Near eutectic Al-Cu droplets were rapidly solidified by Impulse Atomization. A wide range of microstructural scales was obtained at different cooling rates and undercoolings. The micrographs of the investigated samples revealed two distinct zones of different structural morphologies: An undulated...

Valloton, J., Bogno, A.-A., Henein, H., Herlach, D.M., Sediako, D.
This paper reports on the undercooling and growth morphology of Al-4.5wt%Cu and Al-4.5wt%Cu-0.4wt%Sc with a focus on the effect of Sc addition. It is found that the addition of Sc reduces the undercoolings of both primary phase and eutectic. In addition, the morphology of the Al-4.5wt%Cu-0.4wt%Sc...

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...

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...

Baker, Kathleen, Macciotta, Renato, Hendry, Michael T, Lefsrud, Lianne M
Efforts related to the safety and performance of oil sands tailings storage and transportation facilities have traditionally focused on preventing catastrophic failures and are well defined by government legislation and industrial best practices. However, a recent death related to ground hazards...
