While creep deformation of nanoporous gold (NPG) was argued to be mainly dislocation
mediated, we show using molecular dynamics simulations of tensile creep of NPG …

In addition to slip by dislocation glide, deformation twinning in small-sized metallic crystals
also exhibits size effect, namely the twinning stress increases with decreasing sample size …

In situ nanomechanics in scanning electron microscope (SEM) and transmission electron
microscope (TEM) has been the gold-standard for direct observation of deformation …

A microcasting process is used to produce high aspect ratio (> 30) monocrystalline pure
aluminium wires with a diameter between 14 and 115 µm. The role of thermal activation in …

At ambient temperature and pressure, most of the semiconductor materials are brittle.
Traditionally, use of confining pressure via indentation or a hydrostatic confining medium …

Excellent stability of plasticity and high strength are acquired in Ti55531 alloy micropillars
via introducing a high density of deformable nanoscale α phase into a β matrix. The yield …

In this paper, the tensile behavior of Ti/Al multilayered nanowire was investigated by
molecular dynamics simulation under a large range of strain rates and temperatures. The …

Stochastic, discontinuous flow is ubiquitous in the plastic deformation of small-volume
metallic materials. We have identified a size-strengthening effect on the stress to initiate the …

Development of high energy density solid-state batteries with Li metal anodes has been
limited by uncontrollable growth of Li dendrites in liquid and solid electrolytes (SEs). This, in …

A stress relaxation method for freestanding thin films is developed based on an on-chip
internal stress actuated microtensile testing set-up. The on-chip test structures are produced …
