Gomes, L.E., Spinelli, J.E., Bogno, A.-A., Gallerneault, M., Henein, H.
An experimental study is reported on heat treating rapid solidified Al-12 wt.% Si alloy with 355-425 m powder size. Fast heat treatments at 813K revealed morphological shifts of eutectic Si from the as-atomized condition to those after annealing. The Si network of the as-atomized samples showed...

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...

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...
