3D Microstructure-Based Finite Element Simulation of ColdSprayed Al-Al2O3 Composite Coatings Under Quasi-Static Compression and Indentation Loading
Download2021-07-27
Sayahlatifi, Saman, Shao, Chenwei, McDonald, André, Hogan, James D.
This study developed microstructure-based finite element (FE) models to investigate the behavior of cold-sprayed aluminum–alumina (Al-Al2O3) metal matrix composite (MMC) coatings subject to indentation and quasi-static compression loading. Based on microstructural features (i.e., particle weight...

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...

Micro-hardness and strain-rate-dependent compressive response of an ultra-light-weight Mg-Li-Al alloy
Download2022-01-15
Li, Haoyang, Shao, Chenwei, Rojas, David Funes, Ponga, Mauricio, Hogan, James D.
A study on the microstructure and composition, micro-hardness and strain-rate-dependent compressive behaviors, and the associated failure mechanisms of an ultra-light-weight Mg-Li-Al alloy were conducted. X-ray diffraction and X-ray photoelectron spectroscopy showed a multi-phase material with...

Shao, Chenwei, Li, Haoyang, Zhu, Yankun, Li, Peng, Yu, Haoyang, Zhang, Zhefeng, Gleiter, Herbert, McDonald, André, Hogan, James D.
Nanostructured materials are being actively developed, while it remains an open question how to rapidly scale them up to bulk engineering materials for broad industrial applications. This study propose an industrial approach to rapidly fabricate high-strength large-size nanostructured metal...

Strain-Rate-Dependent mechanical behavior of a non-Equimolar CoCrFeMnNi high entropy alloy with a segmented coarse grain structure
Download2022-03-01
Li, Haoyan, Shao, Chenwei, Orhan, Okan K., Rojas, David Funes, Ponga, Maricio, Hogan, James D.
The mechanical response of a Co11.3Cr20.4Fe22.6Mn21.8Ni23.9 (wt%) high entropy alloy with a segmented coarse grain structure is investigated using strain-rate-dependent uniaxial compression experiments. The composition is verified using ab-initio simulations by examining thermal stability through...
