Abstract The transformation induced plasticity phenomenon occurs when one phase transforms to another one during plastic deformation, which is usually diffusionless. Here we present elemental partitioning-mediated crystalline-to-amorphous phase trans

It is practically difficult to find titanium sponges with low and stable aluminum impurities on the market even though it is the precondition to prepare high-purity titanium. Analysis indicates that almost all the aluminum impurities in the titanium

Abstract To alleviate the mechanical instability of major shear bands in metallic glasses at room temperature, topologically heterogeneous structures were introduced to encourage the multiplication of mild shear bands. Different from the former atten

Understanding deformation of Mg along the c-axis is important for wrought processing of Mg. Here the authors report deformation graining in submicron single crystal Mg where the initial single crystal evolves into ultrafine grains that rejuvenates di

Hydrogen induced plasticity has been found in metallic glasses; however, the underlying mechanism remains unclear. Herein, we studied a Cu-Zr metallic glass charged in a hydrogen atmosphere inside an environmental transmission electron microscope. Co

Inspired by the traditional Czochralski method of growing single crystal from liquid, the authors demonstrated that at nanoscale, metallic nanowires including Al, Ag, Cu and Sn can be controllably grown from the surface of a hot solid, by simply draw

Tungsten (W) nanowires have a wide range of chemical, electronic, and mechanical applications. However, the modulus and strength of traditional W nanowires are quite low, and how to improve their mechanical performance remains a challenge. Here, we d

Coherent twin boundaries (CTBs) in face-centered cubic metals are usually considered unable to slide at room temperature. Here, the authors use in situ transmission electron microscopy and molecular dynamics to show CTB sliding in copper nanopillars

Hydrogen gas can drive detachment of protective surface oxides from metal substrates and this process is accelerated at moderately elevated temperatures relevant to applications. Here the authors use environmental transmission electron microscopy to
