Despite being strong with many outstanding physical properties, tungsten is inherently brittle
at room temperature, restricting its structural and functional applications at small scales …

Hard tungsten carbide (WC) with brittle behavior is frequently applied for mechanical
purposes. Here, ultralarge elastic bending deformation is reported in defect‐rare WC [0001] …

Recent efforts dedicated to the mitigation of tungsten (W) brittleness have demonstrated that
tungsten fiber-reinforced composites acquire extrinsic toughening even at room …

Large-scale atomistic simulations are performed to study tensile and compressive ⟨ 112 ⟩⟨
112⟩ loading of single-crystalline nanowires in body-centered cubic tungsten (W). Effects of …

Tungsten-copper composites are used in harsh environments because of their superior
material properties. This work addresses a tungsten-copper composite made of 20 wt …

Twin boundaries (TBs) are assumed to be obstacles to dislocation motion and increase the
strength of metals. Here, we report the abnormal phenomenon that TBs reduce the strength …

Refractory tungsten (W) is notoriously brittle at room temperature, which restricts its
workability and narrows the temperature range of critical applications. Here, we report a …

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 …

The most stable structures of three ultrathin tungsten nanowires were predicted by the
simulated annealing basin-hopping method (SABH) with the penalty algorithm. The …

The nanoindentation results in this work showed that the one-dimensional single crystal
tungsten microwhiskers fabricated by vapor deposition possess unique yielding behavior …
