Thermally activated deformation of metals

JOM, 1964
The dynamic nature of the plastic deformation of metals and its relation to specific thermally activated dislocation mechanisms are discussed. Experimental techniques for evaluating the deformation parameters needed to identify the rate-controlling dislocation mechanism are described.

Lattice thermal conductivity of deformed crystals

Physica B+C, 1988
Abstract Double time Green functions are used to calculate the effect of mass difference and phonon-phonon scattering processes on the static dislocation scattering processes. It is found that when the presence of static dislocation scattering is simultaneously considered with: (i) the mass difference scattering — an additional scattering term is ...

Coupling of elastic and thermal deformations I

Applied Scientific Research, 1958
The general solution for the stress and temperature distribution in an isotropic thermoelastic solid occupying the half space has been given when the classical heat conduction equation is suitably modified to take into account the effect of variation of strain on the variation of temperature, the boundary of the solid being assumed to be stress-free ...

Deformations and Thermal Modifications of Imogolite

2016
Abstract Imogolites, which are aluminosilicate or aluminogermanate nanotubes, are usually known as cylindrical nanotubes. However, in powders, deformations or further structural modifications of these nanotubes occur due to intertube interactions or under the action of temperature.

Deformation of Graphite by Thermal Cycling

Journal of Applied Physics, 1963
The dimensional changes which occur when graphite specimens are thermally cycled under constant torque have been measured. It is shown that internal stresses due to the anisotropic thermal expansion of individual component crystallites cause strain increments to appear which are a function of the temperature change—not of the absolute temperature.

TRANSIENT THERMAL DEFORMATION IN ELECTRICAL BRUSHES

Journal of Thermal Stresses, 1981
The development of a numerical analysis is outlined for an electric current collector or brush treated as a thin half-disk, which has a small contact patch near the center of its straight edge. A quasi-steady electric current is applied, providing a distributed heat source which leads to a transient temperature field, At each time interval, the ...

Thermal deformation in frictionally heated contact

Wear, 1980
Abstract When sliding occurs with significant frictional heating thermoelastic deformation may lead to a transition from smoothly distributed asperity contact to a condition where the surfaces are supported by a few thermal asperities. This circumstance may be associated with a transition to a condition of severe wear because of the elevated contact ...

Piston Thermal Deformation and Friction Considerations

SAE Technical Paper Series, 1982
<div class="htmlview paragraph">The piston assembly is generally believed to account for a large percentage of the total engine mechanical power loss. Maintaining a proper running skirt profile and skirt-to-bore clearance at operating temperature is essential in piston friction reduction.
