This results in a higher density of dislocation interactions and a more complex dislocation network, which in turn enhances work hardening. The increased work hardening rate contributes to improved strength, ductility, and toughness in the material. We further studied the evolution of the average ...
after a critical Td density is reached such that adjacent trimer configurations appear on the surface (red particles Fig. 2g), tip-down insertion of a 4th Td is favorable (red particles Fig. 2h) and thus 2D assembled phases can nucleate. To test this, we experimentally roughened Si ...
and surface energies for various interatomic potentials with those from density functional theory calculations to examine how well these more complicated planar faults and surface energies are captured and whether any deformations are energetically competitive with the {111}112 slip observed in FCC ...
Generalized planar fault energy (GPFE) curves are widely used to evaluate the deformation behavior of metals and alloys. In the present work, a systematic analysis of the microscopic plastic deformation mechanism of face-centered cubic Al in comparison to Cu was conducted based on GPFE curves gen...
We do Density Functional Theory based total-energy calculations of the L12 phase in Co3X and Ni3X compounds, X being a transition metal element. The lattice parameters, magnetic moments and formation enthalpies are determined and compared with the available experimental data. The (111) superlattice...

Because of the L10ordered tetragonal structureof gamma TiAl, only the 1/6[11?2] Shockley partial ina given (111...

Loessial soil is the main soil type in the watershed and is mainly composed of 65% sand, 24% silt and 11% clay by weight [49]. Because of the loose soil particles and the poor erosion resistance, the soil is prone to erosion [8]. The study area shows a landscape of high-density ...
As stated in [16], the information density that is contained in the uncertainty matrix is too high for users who only want a single number. In addition, the uncertainty matrix cannot easily be used for the decision of either acceptance or rejection. Evaluations of measurement uncertainty should...
