Recoverable plasticity in penta-twinned metallic nanowires governed by dislocation nucleation and retraction
There has been relatively little study on time-dependent mechanical properties of nanowires, in spite of their importance for the design, fabrication and operation of nanoscale devices. Here we report a dislocation-mediated, time-dependent and fully reversible plastic behaviour in penta-twinned silver nanowires. In situ tensile experiments inside scanning and transmission electron microscopes s...
متن کاملAre rate sensitivity and strength effected by cross-slip in nano-twinned fcc metals
Synthesis of nano-twinned pure Cu by Lu et al. [L. Lu, R. Schwaiger, Z. W. Shan, M. Dao, K. Lu, S. Suresh, Nano-sized twins induce high rate sensitivity of flow stress in pure copper, Acta Mater. 53 (2005) 2169–2179] has produced materials with extremely attractive properties of combined high strength, strain rate sensitivity, and ductility adequate for applications. This note explores the unde...

متن کاملDislocation creation and void nucleation in FCC ductile metals under tensile loading: A general microscopic picture
Numerous theoretical and experimental efforts have been paid to describe and understand the dislocation and void nucleation processes that are fundamental for dynamic fracture modeling of strained metals. To date an essential physical picture on the self-organized atomic collective motions during dislocation creation, as well as the essential mechanisms for the void nucleation obscured by the e...
متن کاملHeterogeneous dislocation nucleation from surfaces and interfaces as governing plasticity mechanism in nanoscale metals
We report the results of constant strain rate experiments on electroplated, single crystalline copper pillars with diameters between 75 and 525 nm. At slow strain rates, 10 3 s , pillar diameters with 150 nm and above show a size-dependent strength similar to previous reports. Below 150 nm, we find that the size effect vanishes as the strength transitions to a relatively size-independent regime...
