Micropillar Compression

AbstractThe modest goal of this short note is to shed some light on the correct interpretation of micro/nanopillar compression experiments. We propose a modification of the way the stress-strain response in such experiments is calculated, aiming at answering open questions pertaining to discrepancies between the elastic moduli values calculated through micropillar compression experiments with those of the bulk materials, as well as the brittle-to-ductile transition in bulk metallic glasses (BMGs) when the size of the pillars is reduced below a certain threshold value.

Structural Applications

MoSi2 has recently been investigated as a potential material for high temperature structural applications. It has excellent oxidation resistance up to 1700°C, a high melting temperature, 2030°C, and a brittle-to-ductile transition temperature at 900-1000°C. WSi2 is isomorphous with MoSi2 and has a body-centered tetragonal unit cell of the space group 14/mmm. The lattice parameters are a=3.20 Å and c=7.84 Å for MoSi2 and a=3.21 Å and c=7.88 Å for WSi2. Therefore, WSi2 was added to MoSi2 to improve its strength via solid solution hardening. The purpose of this study was to investigate the slip systems in polycrystalline MoSi2/WSi2 alloys.
