homologous temperature

Such a state is usually achieved at high homologous temperature, typically half the absolute melting point.

It usually takes place at high homologous temperatures (i.e. within about a tenth of its absolute melting temperature).

Pressure solution operates at moderate homologous temperatures and relatively low strain-rates and requires the presence of a pore fluid.

Homologous temperature expresses the temperature of a material as a fraction of its melting point temperature using the Kelvin scale.

Nabarro-herring creep acts at high homologous temperatures and is grain size dependent with the strain-rate inversely proportional to the square of the grain size.

It forms discrete, micrometre-sized cubic particles at grain boundaries and triple points, and prevents grain growth by Ostwald ripening up to very high homologous temperatures.

Grain Boundary Sliding is one of the deformation mechanisms of materials which includes displacement of grains against each other at high homologous temperature and low strain rate.

This is a mechanism that operates under low to moderate homologous temperatures, low confining pressure and relatively high strain rates and involves fracturing, sliding and rolling of fragments.

Deformation mechanism maps consist of some kind of stress plotted against some kind of temperature axis, typically stress normalised using the shear modulus versus homologous temperature.

So-called structure zone models were developed to describe the micro structure and ceramics of thin films as a function of the homologous temperature T that is the ratio of deposition temperature over melting temperature.

The active deformation mechanism in a material depends on the homologous temperature, confining pressure, strain rate, stress, grain size, presence or absence of a pore fluid, presence or absence of impurities in the material.
