Effect of Impurities on the Internal Friction Spectrum of Magnesium after Plastic Deformation
We have studied the impurity effect on the internal friction spectrum, with two different samples magnesium 4N and magnesium 6N containing zinc and iron : for the sample 4N we observe a broad peak depending on the oscillation strain amplitude : this peak shifts towards low temperature when the amplitude increases. for the sample 6N containing zinc and iron, the internal friction spectrum is dif...
متن کاملDependence of Internal Friction on Folding Mechanism
An outstanding challenge in protein folding is understanding the origin of "internal friction" in folding dynamics, experimentally identified from the dependence of folding rates on solvent viscosity. A possible origin suggested by simulation is the crossing of local torsion barriers. However, it was unclear why internal friction varied from protein to protein or for different folding barriers ...
متن کاملEffect of internal friction on biofilament dynamics.
We consider biofilaments-flexible multimolecule structures common in cell biology-and show how "internal" friction associated with either conformational fluctuations or with fluid flow through narrow pores inside the filaments can dominate the external hydrodynamic friction usually considered to be the main energy dissipation process. The signature of this is wave-number-independent relaxation ...
متن کاملApplication of Internal Friction to Analysis of Plastic Behaviour of Crystals
A relationship between dislocation internal friction, microplastic and macroplastic behaviour of crystals has been considered. Main attention has been paid to the shape of the dislocation hysteresis responsible for the amplitude-dependent internal fiction (ADIF) and to a comparison between the macroyield stress c, and microyield stress G, evaluated &om the ADIF. It is shown that the same functi...
