Internal Friction Of Bend-Deformed Nanocrystalline Nickel By Mechanical Spectroscopy

, 2008
Internal friction of nanocrystalline nickel is investigated by mechanical spectroscopy from 360 K to 120 K. Two relaxation peaks are found when nanocrystalline nickel is bent up to 10% strain at room temperature and fast cooling. However, these two peaks

Dependence of Internal Friction on Folding Mechanism

, 2016
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.

Measurement of the Indentation Modulus and the Local Internal Friction in Amorphous SiO2 Using Atomic Force Acoustic Microscopy

Archives of Metallurgy and Materials, 2016
For the past two decades, atomic force acoustic microscopy (AFAM), an advanced scanning probe microscopy technique, has played a promising role in materials characterization with a good lateral resolution at micro/nano dimensions.

Internal Friction of Cast Graphite-Magnesium Composites

, 1988
Internal friction behavior in cast 8-ply [0°1 P55Gr/Mg-0.6%Zr alloy and P55Gr/Mg-1%Mn composites as a function of vibratory strain amplitude was measured at 80 kHz using a Marxtype piezoelectric composite oscillator.

Fluidized States of Vibrated Granular Media Studied by Mechanical Spectroscopy

We investigate the jamming transition observed in vibrated granular systems composed of millimeter size glass beads. When a granular system is submitted to vibrations with decreasing intensity, it evolves in a way similar to glass-forming liquids: from a

On the Internal Friction of Ferromagnetic Substances

, 2010
application/pdfIn ferromagnetic substance, the origin of internal friction under low stress amplitude has been considered to be due to two kinds of eddy currents, the first named macroscopic eddy current was studied by Brown and its theoretically ...

Internal Friction and Microstructure of Ti and Ti-Mo Alloys Containing Oxygen

Archives of Metallurgy and Materials, 2016
Ti-Mo alloys are promising materials for use as biomaterials, because these alloys have excellent corrosion resistance and a good combination of mechanical properties such as fatigue, low elastic modulus, hardness, and wear resistance.
