Determining the sound velocity of iron under extreme thermodynamic conditions is essential for a proper interpretation of seismic observations of the Earth's core but is experimentally …
We performed room-temperature sound velocity and density measurements on a polycrystalline alloy, Fe0. 89Ni0. 04Si0. 07, in the hexagonal close-packed (hcp) phase up …

We investigate the equation of state and elastic properties of hcp iron at high pressures and high temperatures using the first-principles linear-response linear-muffin-tin-orbital method …
We carried out sound velocity and density measurements on solid hcp-Fe and an hcp-Fe–Si alloy with 9 wt.% Si at 300 K up to∼ 170 and∼ 140 GPa, respectively. The results allow us …

We performed sound velocity and density measurements on polycrystalline hexagonal close- packed (hcp) iron at simultaneous high pressure and high temperature, up to 93GPa and …
Previously measured in situ x-ray diffraction is used to assess the development of internal elastic strains within grains of a sample of polycrystalline cobalt plastically deformed up to a …
The characterization of elastic strain and stress at the grain level is becoming an important route for validating meso-and nano-scale numerical models. The response of a grain to a …
The superhard ReB2 system is the hardest pure phase diboride synthesized to date. Previously, we have demonstrated the synthesis of nano-ReB2 and the use of this …
We present a multitechnique approach to experimentally determine the elastic anisotropy of polycrystalline hcp Fe at high pressure. Directional phonon measurements from inelastic X …
