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...

Wiskel, J.B., Li, X., Ivey, D.G., Henein, H.
Quantitative X-ray diffraction characterization of four (4) X80 and three (3) X100 microalloyed steels was undertaken. The effect of through thickness position, processing parameters and composition on the measured crystallite size, microstrain and J index (relative magnitude of crystallographic...

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)...

Effect of strain rate on tribological properties of pre-deformed alloys via work function analysis
DownloadFall 2018
In industries such as automobile, aerospace and shipping, components made of magnesium and copper alloy could have the chance to bump against other objects during transportation applications. The damage caused by local deformation at high strain rates when other damage processes are involved,...
