Microcompression tests were performed on focused-ion-beam-machined micropillars of several body-centered-cubic metals (W, Mo, Ta, and Nb) at room temperature. The …
Previous research has shown that body-centred cubic (bcc) metals exhibit a smaller size dependence of strength than what is commonly observed in face-centred cubic (fcc) metals …

The size effect in body-centered cubic metals is comprehensively investigated through micro/nano-compression tests performed on focused ion beam machined tungsten (W) …

Recently, much work has focused on the size effect in face centered cubic (fcc) structures, however few pillar studies have focused on body centered cubic (bcc) metals. This paper …

Recent micropillar compression tests of fcc and bcc single crystals have shown that 'Smaller is Stronger'even in the absence of significant strain gradients, an effect that is empirically …
Abstract Compression tests of< 1 1 1>-oriented LiF single-crystal micropillars 1–5 μm in diameter were carried out from 25° C to 250° C. While the flow stress at ambient temperature …
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 …

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

We evaluate the extent to which two mechanisms contribute to the observed size effect of the ultimate yield strength of micropillars of diameters in the range of 1–30μm: dislocation pile …
