High-throughput assessment of the microstructural stability of segregation-engineered nanocrystalline Al-Ni-Y alloys
W. Streit Cunningham, Jungho Shin, Tianjiao Lei +2
Segregation engineering has emerged as a promising pathway towards designing thermally stable nanocrystalline alloys with enhanced mechanical properties. However, the compositional…
Intermetallic particle heterogeneity controls shear localization in high-strength nanostructured Al alloys
Tianjiao Lei, Esther C. Hessong, Jungho Shin +2
The mechanical behavior of two nanocrystalline Al alloys, Al-Mg-Y and Al-Fe-Y, is investigated with in-situ micropillar compression testing. Both alloys were strengthened by a hier…
Growth and structural transitions of core-shell nanorods in nanocrystalline Al-Ni-Y
Tianjiao Lei, Mingjie Xu, Jungho Shin +2
Unique nanorod precipitates with a core-shell structure are found to nucleate from the grain boundaries of a bulk nanocrystalline Al-Ni-Y alloy fabricated via powder consolidation,…
Bulk nanocrystalline Al alloys with hierarchical reinforcement structures via grain boundary segregation and complexion formation
Tianjiao Lei, Jungho Shin, Daniel S. Gianola +1
Grain size engineering, particularly reducing grain size into the nanocrystalline regime, offers a promising pathway to further improve the strength-to-weight ratio of Al alloys. U…
Electron Backscattered Diffraction using a New Monolithic Direct Detector: High Resolution and Fast Acquisition
Fulin Wang, McLean P. Echlin, Aidan A. Taylor +6
A monolithic active pixel sensor based direct detector that is optimized for the primary beam energies in scanning electron microscopes is implemented for electron back-scattered d…
