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…
Strengthening from dislocation restructuring and local climb at platelet linear complexions in Al-Cu alloys
Pulkit Garg, Daniel S. Gianola, Timothy J. Rupert
Stress-driven segregation at dislocations can lead to structural transitions between different linear complexion states. In this work, we examine how platelet array linear complexi…
Dislocation breakaway from nanoparticle array linear complexions: Plasticity mechanisms and strength scaling laws
Divya Singh, Daniel S. Gianola, Timothy J. Rupert
Linear complexions are stable defect states, where the stress field associated with a dislocation induces a local phase transformation that remains restricted to nanoscale dimensio…
Binary nanocrystalline alloys with strong glass forming interfacial regions: Complexion stability, segregation competition, and diffusion pathways
Tianjiao Lei, Esther C. Hessong, Daniel S. Gianola +1
Stabilization of grain structure is important for nanocrystalline alloys, and grain boundary segregation is a common approach to restrict coarsening. Doping can alter grain boundar…
