Reports from Michigan State University Highlight Recent Findings in Nanowires (Oxidation-assisted ductility of aluminium nanowires)

August 15, 2014

By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Nanowires are presented in a new report. According to news reporting from East Lansing, Michigan, by NewsRx journalists, research stated, "Oxidation can drastically change mechanical properties of nanostructures that typically have large surface-to-volume ratios. However, the underlying mechanisms describing the effect oxidation has on the mechanical properties of nanostructures have yet to be characterized."

The news correspondents obtained a quote from the research from Michigan State University, "Here we use reactive molecular dynamics and show that the oxidation enhances the aluminium nanowire ductility, and the oxide shell exhibits superplastic behaviour. The oxide shell decreases the aluminium dislocation nucleation stress by increasing the activation volume and the number of nucleation sites. Superplasticity of the amorphous oxide shell is due to viscous flow as a result of healing of the broken aluminium-oxygen bonds by oxygen diffusion, below a critical strain rate."

According to the news reporters, the research concluded: "The interplay between the strain rate and oxidation rate is not only essential for designing nanodevices in ambient environments, but also controls interface properties in large-scale deformation processes."
