    • n annealing The process or art of treating substances by means of heat, so as to remove their brittleness and at the same time render them tough and more or less elastic. In general, these results are obtained by heating to a high temperature and then cooling very gradually. All glassware, china, etc., which is to be subjected to great changes of temperature should be thus treated. The working of iron and steel by hammering, bending, rolling, drawing, etc., tends to harden them and make them brittle, and the original properties are restored by annealing. Steel plates and dies for bank-note printing and the like are annealed in a close box with iron filings or turnings, lime, or other substances, and are thus freed from carbon and reduced to pure soft iron, in which state they will readily take, under pressure, the finest engraving from a hardened plate or die. They are then hardened again to the degree necessary for their use in printing. Steel for engraving dies is commonly annealed by heating it to a bright cherry-red color, and cooling it gradually in a bed of charcoal.
    • n annealing Same as tempering.
    • n annealing A founders' term for the slow treatment of the clay or loam cores for castings, which, after having been dried, are burned or baked, and then are slowly cooled.

In poetry:

And sprung from that recurrent storm,
The youthful world exultant wheels,
Where slow Eternity anneals
The manacles of Time and Form;
"The Testimony of the Suns" by George Sterling

Making thy life to shine within
The holy preacher's; then the light and glorie
More rev'rend grows, and more doth win;
Which else shows watrish, bleak, and thin.
"The Windows" by George Herbert
One throb of joy, one pulse of pain,
One moment's thought between the twain:
A heart that broke—a death that healed,
So wretched that it half annealed;
Yet sadder fate on Lindsay's head—
A heart that beat although 'twas dead. VI.

The essence of the result is that the law of an edge oriented reinforced random walk coincides with the annealed laws of a RWRE if the law of reinforcement satisfies the following condition: at one point the probability of a sequence of successive moves depends only on the number of each type of move.

As a corrolary, the uniqueness of this moment problem implies that the annealed law determines the quenched law for RWRE.

We propose that this may represent the correct mean-field limit of the model rather than the annealed random neighbor version.
A Nonconservative Earthquake Model of Self-Organized Criticality on a Random Graph
To overcome the limitation of relying almost exclusively on computer simulation results, it has sometimes been useful to consider an annealed random neighbor (RN) version of the model [15–18], where each site interacts with randomly chosen sites instead of its nearest neighbors on the lattice.
A Nonconservative Earthquake Model of Self-Organized Criticality on a Random Graph
Contrary to the RN case, in a random graph the choice of neighbors is not annealed but quenched, so that spatial correlations can develop.
