Theaverage density of Earthis 5.515 g/cm3. Because theaverage density of surfacematerial is only around 3.0 g/cm3, we must conclude thatdensermaterialsexist within Earth's core.Seismic measurementsshow that the core is divided into two parts, a "solid"inner corewith a radius of ≈1,220 km...
In Fig. 4, the leading basal partial dislocations are found to have an Burgers vector of 2/3[11¯00] and the corresponding SFs are intrinsic (I 2 type)36. The density of basal SFs increases with increasing strain, and these deformation-induced basal SFs span through the entire grain ...

The Earth’s inner core contains iron (Fe) as the main component and approximately 5–10 weight percent (wt%) of nickel (Ni)1,2. However, it is well known that the density of the inner core is approximately 4% lower than that of pure hexagonal close-packed (hcp) iron3 or approximate...

Density had little effect on the wear of sintered iron at a low sliding amplitude of 0.05 mm, wear was slight and characterised by the formation of a little amount of brown α-Fe2O3 on the surfaces. The effect of density on wear increased with increasing sliding amplitude and it was ...
