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...

INTERNAL FRICTION OF DEFORMED NaCL

Internal friction of deformed oriented NaCl single crystals has been measured as a function of flow stress, strain amplitude, frequency, temperature and divalent doping. In pure NaCl af er deformation a maximum of internal friction PI is observed at low temperatures. With increasing 1+ Sr doping a second but much weaker peak P2 appears at higher temperatures. The dependencies of PI on the...

Internal friction in enzyme reactions.

The empirical concept of internal friction was introduced 20 years ago. This review summarizes the results of experimental and theoretical studies that help to uncover the nature of internal friction. After the history of the concept, we describe the experimental challenges in measuring and interpreting internal friction based on the viscosity dependence of enzyme reactions. We also present spe...
