Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201500377-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The trend from "smaller is stronger" to "size‐independent strength plateau"</bold> is observed in the compression of spherical iron nanoparticles. When the diameter of iron nanospheres is less than a critical value, the maximum contact pressure saturates at 10.7 GPa, corresponding to a local shear stress of ≈9.4 GPa, which is comparable to the theoretical shear strength of iron. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjrk4gxqg" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
