Structure FactorThe effect of the Peierls stress on the ultimate tensile stress and uniform strain prior to the formation of a neck during stretching of metals and alloys with bcc structure is theoretically analyzed. The analysis is based on the equation for the variation of the dislocation ...
The high mobilities of dopants before clustering has taken place, especially when compared to binary hard sphere systems, in these weak bcc crystals is the determining factor which allows efficient lowering of the systems free energy by the formation of dopant clusters and pockets of liquid dopant....
Aberrations in the ion trajectories near the specimen surface are an important factor in the spatial resolution of the atom probe technique. Near the boundary between two phases with dissimilar evaporation fields, ion trajectory overlaps may occur, leading to a biased measurement of composition in the...
The plastic-zone radius, Rpl, may be scaled to the geometric contact radius, ac=2Rd−d2=8 nm, to yield the plastic-zone size factor f=Rpl/ac in order to allow comparison to other indenter radii R and indentation depths d. Table 2 assembles these values for the crystals studied here...

The misorientation range where W diverges predicted by PFC simulations is much smaller than the range predicted by MD simulations when the small dimensionless parameter e of the PFC model is matched to liquid structure factor properties. However, it agrees well with MD simulations with a lower e ...

A crystal structure has ordered atom sites, and the arrangement and positioning of these atoms will give rise to different properties of the material. The same arrangement is present in the whole crystal structure, as it is a recurrence of the smallest block o...
solidUsing Path Integral Monte Carlo and the Maximum Entropy method, we calculate the dynamic structure factor of solid 3 He in the bcc phase at a finite temperature of T=1.6K and a molar volume of 21.5cm 3 . From the single phonon dynamic structure factor, we obtain both the longitudinal...
