Nanocrystalline materials are widely used for their special properties, including structural applications with high strength. The strength enhancement comes from the inhibited …
The size effect in body-centered cubic metals is comprehensively investigated through micro/nano-compression tests performed on focused ion beam machined tungsten (W) …
We compare mechanical strength of fcc gold and bcc molybdenum single crystal pillars of sub-micrometer diameter in uniaxial compression tests. Both crystals show an increase of …
Uniaxial tension and compression experiments on [001] and [011] oriented molybdenum nano-pillars exhibit tension–compression asymmetry, a difference in attained stresses in …
