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…

Local structural ordering determines the mechanical damage tolerance of amorphous grain boundary complexions
Pulkit Garg, Timothy J. Rupert
Amorphous grain boundary complexions act as toughening features within a microstructure because they can absorb dislocations more efficiently than traditional grain boundaries. Thi…

Grain incompatibility determines the local structure of amorphous grain boundary complexions
Pulkit Garg, Timothy J. Rupert
Amorphous grain boundary complexions lack long-range crystalline order but are not featureless, as distinct gradients in structural short-range order have been reported through the…
