High strength particulate aluminum matrix composite design: Synergistic strengthening strategy
Download2021-06-01
Shao, Chenwei, Lo, Calvin, Bhagavathula, Kapil, McDonald, André, Hogan, James D.
Aluminum-alumina (Al–Al2O3) composites with ultrahigh strength were designed by combining dispersion strengthening via the addition of Al2O3 particles and matrix strengthening via in situ strain hardening. Cold spraying additive manufacturing technology was applied to fabricate the composites....

Rojas, David Funes, Li, Haoyang, Orhan, Okan K., Shao, Chenwei, Hogan, James D., Ponga, Maricio
We present a combined experimental and computational investigation of the mechanical properties of a CoCrFe0.75NiMo0.3Nb0.125 (composition in molar ratio) high-entropy alloy additively manufactured via cold spray. We find that the sprayed alloy exhibits extraordinary mechanical properties under...

Quasi-static confined uniaxial compaction of granular alumina and boron carbide observing the particle size effects
Download2019-10-25
Nicewicz, Piotr, Peciar, Peter, Macho, Oliver, Sano, Tomoko, Hogan, James D.
The quasi-static confined uniaxial compaction of granular alumina and boron carbide was studied, and the effect of triaxial stress on the materials as a function of increasing particle size was observed. The average particle sizes studied for granular alumina were 170 ± 63, 230 ± 55, 330 ± 67,...
