Abstract

<abstract abstract-type="graphical"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Deformed materials usually show a hardening behavior, i.e. enhanced strength accompanied with reduced ductility. Here, we report an extraordinary toughening behavior in cryorolled Zr, i.e. a simultaneous enhancement of the strength and ductility with strain. This unusual increase of ductility results from the motion of preexisting high‐density dislocations in tensile processes. The high‐density dislocations also contribute to the enhanced strength. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4sr4hn25" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
