Title: Shear banding mechanism in compressed nanocrystalline ceramic nanopillars

Abstract

Localization of deformation in shear bands is widely observed preceding intense damage and fracture in ductile or granular materials. However, mechanisms about how shear bands form are generally not known. Here, we show that nanocrystalline ceramic (NCC) nanopillars of ZrN fracture by shear banding under compression. The microstructure evolution of entire shear banding process was in situ monitored by electron imaging and diffraction. Results show that the nanopillars deform through a series of granular activities due to intermittent nucleation and propagation of dislocations. The stress drops associated with the dislocation activities are relatively small since dislocation avalanches are restricted in NCCs because of the effect of nanograin size. Localized and cooperative granular activities, as well as nanocracks, are discovered in the regions where shear bands form. A model about shear band and nanocrack formation is proposed. These findings thus demonstrate for the first time of spatial and temporal nature of intermittent granular activities, leading to shear band formation in NCCs.

Suppression of shear banding in amorphous ZrCuAl nanopillars by irradiation

Journal Article Qiran, Xiao ; Liping, Huang ; Yunfeng, Shi - Journal of Applied Physics

Using molecular dynamics simulations, model Zr{sub 50}Cu{sub 40}Al{sub 10} metallic glass (MG) nanopillars were subjected to simulated irradiation processes followed by uniaxial compression tests. As the intensity or dosage of irradiation increases, the plastic deformation mode of the MG nanopillars transits from localized shear banding to homogeneous shear flow. The suppression of shear banding in MG nanopillars is due to irradiation-induced structural disordering. Furthermore, a correlation is found between the average potential energy of MG nanopillars and their deformation modes, common to both irradiation processing and thermal processing. Our results imply that the homogeneous shear flow observed in experimental MGmore »« less

Discrete shear band plasticity through dislocation activities in body-centered cubic tungsten nanowires

Journal Article Wang, Jiangwei ; Wang, Yanming ; Cai, Wei ; ... - Scientific Reports

Shear band in metallic crystals is localized deformation with high dislocation density, which is often observed in nanopillar deformation experiments. The shear band dynamics coupled with dislocation activities, however, remains unclear. Here, we investigate the dynamic processes of dislocation and shear band in body-centered cubic (BCC) tungsten nanowires via an integrated approach of in situ nanomechanical testing and atomistic simulation. We find a strong effect of surface orientation on dislocation nucleation in tungsten nanowires, in which {111} surfaces act as favorite sites under high strain. While dislocation activities in a localized region give rise to an initially thin shear band,more »« less

High resolution transmission electron microscopic in-situ observations of plastic deformation of compressed nanocrystalline gold

Journal Article Wang, Guoyong ; Lian, Jianshe ; Jiang, Qing ; ... - Journal of Applied Physics

Nanocrystalline (nc) metals possess extremely high strength, while their capability to deform plastically has been debated for decades. Low ductility has hitherto been considered an intrinsic behavior for most nc metals, due to the lack of five independent slip systems actively operating during deformation in each nanograin. Here we report in situ high resolution transmission electron microscopic (HRTEM) observations of deformation process of nc gold under compression, showing the excellent ductility of individual and aggregate nanograins. Compression causes permanent change in the profile of individual nanograins, which is mediated by dislocation slip and grain rotation. The high rate of grainmore »« less

Deformation structures in ball milled copper

Journal Article Huang, J Y ; Wu, Y K ; Ye, H Q - Acta Materialia

The deformation structures of copper powder induced by ball milling were studied in detail by using high resolution electron microscopy. It was found that copper powder after 20 h of milling shows the formation of shear bands and a number of mechanical twins. The observed twins belong to two types, i.e. multiple twins and high-order ones. It is suggested that Venables` model on mechanical twins in face-center-cubic metals is reasonable in this case. The generation of mechanical twins could be explained as follows: the shear stress (P{sub max}) induced by ball milling exceeds the critical shear stress for twinning ({tau});more »« less

Novel shear mechanism in nanolayered composites

Journal Article Mara, Nathan ; Bhattacharyya, Dhriti ; Hirth, John P ; ... - Nature Materials

Recent studies have shown that two-phase nanocomposite materials with semicoherent interfaces exhibit enhanced strength, deformability, and radiation damage resistance. The remarkable behavior exhibited by these materials has been attributed to the atomistic structure of the bi-metal interface that results in interfaces with low shear strength and hence, strong barriers for slip transmission due to dislocation core spreading along the weak interfaces. In this work, the low interfacial shear strength of Cu/Nb nanoscale multilayers dictates a new mechanism for shear banding and strain softening during micropillar compression. Previous work investigating shear band formation in nanocrystalline materials has shown a connection betweenmore »« less
