Subtalar Dislocations

open access: goldJAAOS: Global Research and Reviews, 2021
Subtalar dislocations are uncommon injuries that involve disruption of the talocalcaneal and talonavicular joints. Whereas medial subtalar dislocations are usually caused by low-energy mechanisms and are reducible by closed means, lateral subtalar dislocations occur due to high-energy trauma, have associated foot injuries, and may require open ...

Dislocation Analysis of Nanoindentation on Different Crystal Planes of 6H-SiC Based on Molecular Dynamics Simulation

open access: yesCrystals, 2022
In order to explore the deformation law of nanoindentation dislocation on different crystal planes of 6H-SiC by cube indenter at high temperature, the (0001), (11¯00) and (21¯1¯0) crystal planes were simulated by molecular dynamics, and changes of ...

Deformation Mechanisms of FCC-Structured Metallic Nanocrystal with Incoherent Twin Boundary

open access: yesMetals, 2021
Incoherent twin boundaries (ITBs) can significantly affect the mechanical properties of twin-structured metals. However, most previous studies have focused on the deformation mechanism of the coherent twin boundary (CTB), and metals with ITB-accommodated

Interactions between Dislocations and Penta-Twins in Metallic Nanocrystals

open access: yesMetals, 2021
Dislocation interactions with twin boundary (TB) have been well-established in nanotwinned metals. Penta-twins, as an extreme of crystal twinning, are tacitly assumed to be more effective at blocking dislocation motions than conventional single or ...

Deformation Behavior of Crystalline Cr–Ni Multilayer Coatings by Using Molecular Dynamics Simulation

open access: yesLubricants, 2022
This work shows the atomic scale deformation behavior of crystalline multilayer coating comprising up to five Cr and Ni layers. A molecular dynamics simulation was conducted to visualize the atomic scale behavior of the multilayer during indentation ...

Unified interpretation of hydrogen-diffusion and various fracture properties in high-pressure hydrogen gas based on trap-site occupancy of hydrogen by dislocation—austenitic stainless steels and low-alloy steels

open access: yesNihon Kikai Gakkai ronbunshu, 2020
A binding energy, EB, and the number of trap sites, NX, of hydrogen trapped in cold-rolled austenitic stainless and quenched-tempered low alloy steels exposed in high-pressure hydrogen gas were determined from a linear relationship between the ...
