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...
