Modulation of structural short-range order due to chemical patterning in multi-component amorphous interfacial complexions
Esther C. Hessong, Zhengyu Zhang, Tianjiao Lei +3
Amorphous interfacial complexions have been shown to restrict grain growth and improve damage tolerance in nanocrystalline alloys, with increased chemical complexity stabilizing th…
Kinetics of Amorphous Defect Phases Measured Through Ultrafast Nanocalorimetry
W. Streit Cunningham, Tianjiao Lei, Hannah C. Howard +2
Recognition of the role of extended defects on local phase transitions has led to the conceptualization of the defect phase, localized thermodynamically stable interfacial states t…
Bulk nanocrystalline Al-Mg-Y alloys with amorphous grain boundary complexions display high strength and compressive plasticity
Tianjiao Lei, Esther Hessong, Brandon Fields +3
Although nanocrystalline alloys regularly exhibit high strengths, their use in structural applications often face challenges due to sample size limitations, unstable microstructure…
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…
Bulk High-Entropy Hexaborides
Mingde Qin, Qizhang Yan, Yi Liu +7
For the first time, a group of CaB6-typed cubic rare earth high-entropy hexaborides have been successfully fabricated into dense bulk pellets (>98.5% in relative densities). The sp…
In situ mechanical testing of an Al matrix composite to investigate compressive plasticity and failure on multiple length scales
Tianjiao Lei, Jenna L. Wardini, Olivia K. Donaldson +1
SiC particle-reinforced Al matrix composites exhibit high strength, high wear resistance, and excellent high-temperature performance, but can also have low plasticity and fracture…
