Enabling plastic co-deformation of disparate phases in a laser rapid solidified Sr-modified Al-Si eutectic through partial-dislocation-mediated-plasticity in Si
Arkajit Ghosh, Wenqian Wu, Bibhu Prasad Sahu +2
Nano-scale eutectics, such as rapid solidified Al-Si, exhibit enhanced yield strength and strain hardening but plasticity is limited by cracking of the hard phase (Si). Mechanisms…
Three-dimensional morphology of an ultrafine Al-Si eutectic produced via laser rapid solidification
Xinyi Zhou, Paul Chao, Luke Sloan +4
Al-Si alloys processed by laser rapid solidification yield eutectic microstructures with ultrafine and interconnected fibers. Such fibrous structures have long been thought to bear…
Mechanism of Local Lattice Distortion Effects on Vacancy Migration Barriers in FCC Alloys
Zhucong Xi, Mingfei Zhang, Louis G. Hector +2
Accurate prediction of vacancy migration energy barriers, , in multi-component alloys is extremely challenging yet critical for the development of diffusional transformation…
Nanoscale deformation mechanics reveal resilience in nacre of Pinna nobilis shell
Jiseok Gim, Noah Schnitzer, Laura M. Otter +7
The combination of soft nanoscale organic components with inorganic nanograins hierarchically designed by natural organisms results in highly ductile structural materials that can…
Strength of Cu-TiN and Al-TiN interfaces from first-principles
S. K. Yadav, R. Ramprasad, J. Wang +2
Using density functional theory (DFT) based first principles calculations, we show that the preferred interfacial plane orientation relationship is determined by the strength of bo…
Anomaly of Film Porosity Dependence on Deposition Rate
Stephen P. Stagon, Hanchen Huang, J. Kevin Baldwin +1
This Letter reports an anomaly of film porosity dependence on deposition rate during physical vapor deposition - the porosity increases as deposition rate decreases. Using glancing…
