Mild-to-wild plastic transition is governed by athermal screw dislocation slip in bcc Nb

Q. Rizzardi et al.

Summary: Plastic deformation in crystals is mediated by the motion of line defects known as dislocations. The conventional understanding of plasticity as a homogeneous process has been challenged by the discovery of long-range correlated and intermittent collective dislocation processes, termed avalanches. In this study, the authors investigate the temperature-dependent microplasticity in body-centered cubic Nb and reveal the dominance of athermal screw dislocation activity during intermittent slip. The results suggest that plasticity can be understood in terms of the coexistence of mild and wild modes of deformation, providing insights for the design of better alloys.

Dislocation avalanches are like earthquakes on the micron scale

Peter Dusan Ispanovity et al.

Summary: The authors reveal similarities between the intermittent deformation process in metallic microsamples and earthquakes by analyzing the emitted elastic waves. The dislocation motion in micropillars is found to resemble a stick-slip process, with local strain bursts of scale-free size distribution. The study also uncovers a two-level structure of plastic events in the acoustic emission data.

Temperature dependent plasticity in BCC micropillars

Nicole K. Aragon et al.

Summary: Recent experiments in micron- or sub-micron metallic pillars have displayed size dependent plasticity, with dislocation dynamics simulations proving useful in studying the temperature dependent plasticity in BCC micropillars. The study showed a change in dislocation source mechanism with temperature, in line with experimental results and theoretical models, while also observing an increase in size dependence with temperature.

How grain boundary characteristics influence plasticity close to and above the critical temperature of ultra-fine grained bcc Ta2.5W

J. Kappacher et al.

Summary: This study revealed that the hardness of low-angle grain boundary samples remained temperature-invariant, while the hardness of high-angle grain boundary samples showed a pronounced temperature dependence. The diffusion of grain boundaries plays a significant role in interfacial stress relaxation, with high-angle grain boundaries suppressing discrete flow characteristics.

Fluctuations in crystalline plasticity

Jerome Weiss et al.

Summary: This paper reviews the long-tailed acoustic signature of dislocation avalanches in HCP materials and the generic intermittent plastic response in micro- and nano-sized systems, independent of their crystallographic symmetry. The physical origin, scaling properties, and emergent behaviors of plastic fluctuations are discussed, along with the ability to temper them by alloying. The paper also explores the size effect and the role of quenched disorder in controlling plastic flow intermittency, opening new perspectives in micro-metallurgy and structural engineering of ultra-small load-carrying elements.
