Even before it broke out, bad weather and commercial dislocations, together with overpopulation in some areas, resulted in worse and more frequent famines than in the past.
The generation of a high-density of Shockley partial dislocations on several different slip systems contributes to the observed ultrahigh ductility, while the formation of sessile stair-rod and Frank partial dislocations (together with the presence of the twin boundaries themselves) explain observations of ultrahigh strength.
At short milling times (t < 200 min), ball collisions lead to crystallite-size decrease by dislocation formation together with a related increase of lattice strain.
The results indicate that a change in the mobile dislocation density, together with thermal softening, has substantial effects on apparent work hardening behavior at high strain rates, although the change in the mobile dislocation density is transcribed at macroscopic scale in the model.
Nanoscaled multilayer structures usually show both high hardness and better wear resistance, correlated with grain refinement, coherency strain hardening, inhibition of dislocation motion, together with an excellent corrosion resistance due to the interruption of coating columnar pinholes and to the combined metal element effect.
A model is proposed which explains the intermediate states in terms of statistical variation of the nucleation site of the complementary 60° dislocation which forms, together with the primary dislocation, a Lomer dislocation at the interface.
With increasing number of cycles, the dislocations are gradually grouped together in planar bands with high dislocation density, surrounded by dislocation-poor areas.
Both processing routes results in ultrafine grained structures which together with dislocation and solid solution strengthening bring about high strength (yield strength exceeds 400 MPa).
In particular, we show that the use of erbium, together with dislocation engineering, could provide useful optical emission and gain at the important 1.5 μm wavelength that dominates optical data transfer.
To compute initial water surface elevation for the tsunami simulation, analytical equations for elastic dislocation by Okada (1985) together with the equation by Tanioka and Satake (1996) were used.
