Deformation Mechanisms in Nanocrystalline Materials,e Hall-Petch law, (2) elastic pseudo perfect plastic response in quasi-static tests, and (3) increasing strain rate sensitivity parameter with decreasing grain size. All of these indicators clearly suggest that the activity of each probable deformation mechanism is likely to exhibit a pronounced size dependence.

,Wofür wir dieses Buch geschrieben haben, The amazing predictive capabilities provided by atomistic simulations are unfortunately limited (1) by their computational cost and (2) by the description of the interaction between atoms via use of an energy potential function.

Grain Boundary Modeling,nse. In general, grain boundaries provide barriers to the motion of dislocations within a grain – this in turns leads to a more pronounced hardening – and can also act as barrier to crack propagation, which can improve the materials’ ductility.

Predictive Capabilities and Limitations of Continuum Micromechanics,is is primarily due to the fact that the scale and boundary conditions involved in molecular simulations are several orders of magnitude different from those in real experiments or of typical polycrystalline domains of interest.

Therefore, models with adequate predicting capabilities must originate from a clear description of the material’s microstructure. Since different processing routes may lead, for example, to materials with different amounts of defects, it is capital t
