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...

Bhagavathula, Kapil Bharadwaj, Meredith, Christopher S., Ouellet, Simon, Romanyk, Dan L., Hogan, James D.
This study presents a comprehensive experimental study of the evolution of Poisson’s ratio and tangent modulus of polymeric foams during rate dependant uniaxial compression. In this study, polyurethane foams with densities of 195 kg/m3, 244 kg/m3, and 405 kg/m3 obtained from PORON (XRD series)...

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...
