Spinelli, J.E., Hearn, W., Bogno, A.-A., Henein, H.
Understanding the influence of rapid solidification conditions on the formed microstructure is important to determine how process conditions affect the final mechanical properties. In this work the rapid solidification of hypoeutectic and hypereutectic Al-xSi (x=10wt. %, 18wt %) alloys was...

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...

Spinelli, J.E., Bogno, A.-A., Henein, H.
Hypereutectic Al-18wt.%Si alloy is widely used in automotive industry as a wear resistant alloy for engine components. However, in the last few years, this traditional composition is being considered for processing by different rapid solidification methods. Positive points include its low thermal...
