anneal

[ə′nēl]
(engineering)
To treat a metal, alloy, or glass with heat and then cool to remove internal stresses and to make the material less brittle. Also known as temper.
(genetics)
To recombine strands of complementary deoxyribonucleic acid that were separated by heating or other means of denaturation.

anneal

To take the brittleness out of metal, plastic or certain carbon composites. Performed in the preparation of new products or in their restoration, annealing is accomplished via a heat treating process.

Reheating the annealed PDO from room temperature to 130[degrees]C revealed a unique thermal transition behavior (Fig.
For the specimens annealed at 200[degrees]C, the Mg content ranged from 600 to 300 counts in the direction from Mg to Al, while the Al content was 50-100 counts in the same direction.
It can be observed from Figure 3(b) that peaks of [beta]-SiC show little difference in fibres annealed both under simulated atmosphere and in dry air.
It was found that the films annealed at 400 and 500[degrees]C exhibited a linear relationship of the ln [sigma] versus[T.sup.-1] plot in the temperature region of 300-500 K in Figure 5, which matches the Arrhenius relationship between dark conductivity and temperature, described as the formula: [sigma] = [[sigma].sub.0] exp(-[E.sub.a]/[k.sub.B]T), where [[sigma].sub.0] is the preexponential factor of conductivity, [E.sub.a] is the conductivity activation energy, and [k.sub.B] is Boltzmann's constant.

Crystallite size increased with annealing more in films deposited by one deposition cycle than by multiple depositions; for the series annealed at 460[degrees]C from 130 to 163 [Angstrom] for the one-deposition-cycle CdS/SnS films and from 130 to 143 [Angstrom] for the three-deposition-cycle ZnS/SnS films.
