The strength of aluminum alloy 2025 (duralumin) micro-pillars is known to be significantly
higher than that of pure Al micro-pillars of comparable sizes since the precipitates present …

Pure metal microspecimens have been found to exhibit strong size dependence of strength,
but alloyed counterparts with a much refined microstructural length scale due to the …

Two-dimensional dislocation dynamics simulations are used to study precipitate
strengthening effects in duralumin micropillars. The results show that a refined …

An anomalously reduced size-dependent strength of commercial-purity aluminum (Al) single-
crystal micropillars with diameters ranging approximately from 1 to 10 μm is reported. High …

The mechanical behavior of bicrystalline aluminum nano-pillars under uniaxial compression
reveals size effects, a stochastic stress–strain signature, and strain hardening. Pillar …

A two-dimensional discrete-continuous scheme (DCS), which couples the motions of
dislocations and diffusion of vacancies, is developed. There are three modules in this …

The size-dependence of the plastic response of single-crystal micropillars at
submicron/micron length scales under compression was investigated using three …

The plastic deformation of micropillars is known to be affected by whether dislocations can
escape easily from the material volume, and the extent to which the dislocations mutually …

Micromechanical tests are performed to investigate the sample size effects on creep
behavior of single crystalline Cu micropillars at room temperature. We report a transition …

Micron-sized metallic crystals are much stronger than their bulk counterparts. However, their
deformation is jerky and they do not strain harden continuously, so that precise metal …
