Deformation twinning is an important plastic carrier competing with the ordinary dislocation
slip in a broad class of crystalline solids, which critically controls the mechanical properties …

It has been well documented that plastic deformation of crystalline and amorphous
metals/alloys shows a general trend of “smaller is stronger”. The majority of the experimental …

Most next-generation Li ion battery chemistries require a functioning lithium metal (Li)
anode. However, its application in secondary batteries has been inhibited because of …

There have been very limited studies on plastic deformation mechanisms in single-
crystalline high-entropy alloys (HEAs) with body-centered cubic (BCC) phases. We …

Abstract Nanoscale three-dimensional (3D) printing of metals and alloys has faced
challenges in speed, miniaturization and deficiency in material properties. Traditional …

We used micropillar compression experiments to study the plasticity of ferrite and martensite
of two commercial dual phase steel grades (DP800). The activation of all three slip plane …

Titanium alloy is prominent in manufacturing of high-performance miniature devices, while
size-affected plastic heterogeneity and asymmetry in micro-scaled deformation are not well …

Both torsion and tensile tests are performed on polycrystalline copper wires with diameters
in the range 20–50μm. A significant size effect in both the initial yielding and the plastic flow …

The strength of metals increases with decreasing sample size, a trend known as the size
effect. In particular, focused ion beam-milled body-centered cubic (BCC) micropillars exhibit …

Power laws are omnipresent and actively studied in many scientific fields, including plasticity
of materials. Here, we report the power-law statistics in the second and subsequent pop-in …
