Phase transformation is an important deformation and blunting mechanism at the crack tip of
body-centered cubic (BCC) metals. The BCC-to-face-centered orthogonal (FCO) …

Phase transformation is rare in pure body-centered cubic (BCC) metals due to the
associated high energy barrier. Here, omega (ω) phase transformation in single-crystal …

A deformation-induced hexagonal ω phase was first observed in pure nanocrystalline body-
centered cubic (bcc) Mo using high-resolution transmission electron microscopy. As the …

With our recently developed deformation device, the in situ tensile tests of single crystal
molybdenum nanowires with various size and aspect ratio were conducted inside a …

Abstract Effects of uniaxial tensile directions on the phase transformations in a nano-sized
face centred cubic (fcc) crystal in iron were studied by molecular dynamics simulations. The …

Molybdenum is a refractory metal that is stable in a body-centred cubic structure at all
temperatures before melting. Plastic deformation via structural transitions has never been …

High-energy ball milling induced hexagonal close-packed (HCP) to face-centred cubic
(FCC) phase transformation in pure hafnium was investigated through x-ray diffraction …

The knowledge regarding anisotropic mechanical behaviors in nanoscale body-centered
cubic (bcc) metals remains obscure. Herein, we report the orientation-dependent ductility in …

This work studies deformation twins in nanocrystalline body-centered cubic Mo, including
the nucleation and growth mechanisms as well as their effects on ductility, through …

Deformation mechanisms of the nanocrystalline body-centered cubic U–Mo alloy were
investigated through molecular dynamics simulations, focusing on the influences of the grain …
