Direct Observation of Sink-Dependent Defect Evolution in Nanocrystalline Iron under Irradiation

Journal Article El Atwani, Osman ; Nathaniel, James ; Leff, Asher C. ; ... - Scientific Reports

Crystal defects generated during irradiation can result in severe changes in morphology and an overall degradation of mechanical properties in a given material. Nanomaterials have been proposed as radiation damage tolerant materials, due to the hypothesis that defect density decreases with grain size refinement due to the increase in grain boundary surface area. The lower defect density should arise from grain boundary-point defect absorption and enhancement of interstitial-vacancy annihilation. In this study, low energy helium ion irradiation on free-standing iron thin films were performed at 573 K. Interstitial loops of a ₀ /2 [111] Burgers vector were directly observed asmore »« less

Radiation damage in nanostructured materials

Journal Article Zhang, Xinghang ; Hattar, Khalid ; Chen, Youxing ; ... - Progress in Materials Science

Materials subjected to high dose irradiation by energetic particles often experience severe damage in the form of drastic increase of defect density, and significant degradation of their mechanical and physical properties. Extensive studies on radiation effects in materials in the past few decades show that, although nearly no materials are immune to radiation damage, the approaches of deliberate introduction of certain types of defects in materials before radiation are effective in mitigating radiation damage. Nanostructured materials with abundant internal defects have been extensively investigated for various applications. The field of radiation damage in nanostructured materials is an exciting and rapidlymore »« less

Grain rotation mediated by grain boundary dislocations in nanocrystalline platinum

Journal Article Wang, Lihua ; Teng, Jiao ; Liu, Pan ; ... - Nature Communications

Grain rotation is a well-known phenomenon during high (homologous) temperature deformation and recrystallization of polycrystalline materials. In recent years, grain rotation has also been proposed as a plasticity mechanism at low temperatures (for example, room temperature for metals), especially for nanocrystalline grains with diameter d less than ~15 nm. Here, in tensile-loaded Pt thin films under a high-resolution transmission electron microscope, we show that the plasticity mechanism transitions from cross-grain dislocation glide in larger grains (d>6 nm) to a mode of coordinated rotation of multiple grains for grains with d<6 nm. The mechanism underlying the grain rotation is dislocation climbmore »« less

Quantitative description of plastic deformation in nanocrystalline Cu: Dislocation glide versus grain boundary sliding

Journal Article Vo, N Q ; Averback, R S ; Bellon, P ; ... - Physical Review. B, Condensed Matter and Materials Physics

Uniaxial plastic deformation of polycrystalline Cu with grain sizes in the range of 5-20 nm was studied by using molecular dynamics computer simulations. We developed a quantitative analysis of plasticity by using localized slip vectors to separate the contributions of dislocation activity from grain boundary sliding. We conclude that the competition between these two mechanisms depends on strain rate and grain size, with the dislocation activity increasing with grain size but decreasing with increasing strain rate. For samples with a 5 nm grain size, dislocations contribute {approx_equal}50% of the total plastic strain during steady state deformation at a rate ofmore »« less
