The process of softening metal. For ferrous metals, that is those containing iron

The process of controlled heating and cooling of a metal. In a wire and cable products, copper and aluminum are annealed to increase flexibility while maintaining adequate strength.

A process, consisting of heating to and holding at a suitable temperature followed by cooling at a suitable rate, used primarily to soften metallic materials, such as steel. This process also simultan [..]

  The pairing of complementary DNA or RNA sequences, via hydrogen bonding, to form a double-stranded polynucleotide. Most often used to describe the binding of a short primer or probe.

Generally synonymous with "hybridize".

(v) bring to a desired consistency, texture, or hardness by a process of gradually heating and cooling

 - The process of controlled heating and cooling of a metal. In wire and cable products, copper and aluminum are annealed to increase flexibility while maintaining adequate strength.

To use heat treatment methods to reduce material hardness.

The controlled process for making glass stronger and less brittle in which the glass is heated and then cooled.

A process of heating glass and then slowly cooling it, which helps relieve internal stress, making the lass less likely to break. Tempered glass is creating using annealing. See also Tempered Glass.

To temper, or relieve mechanical stress through heat and gradual cooling.  Annealing copper renders it less brittle.

To heat a metal and to cool it in such a fashion as to toughen and soften it. Brass or copper is annealed by heating to a cherry red and dipping suddenly into water while hot. Iron or steel is slowly [..]

The sustained heating of a material such as steel or glass at aspecific high temperature, followed by gradual cooling, this is done to eliminate weakness or to produce other qualities. The pairing of complementary DNA or RNA sequences, via hydrogenbonding, to form a double-stranded molecule. Mostoften used to describe the binding of a short primer [..]

To heat and cool steel so that the metal is not brittle.

The process of using heating and slow cooling to toughen steel (or glass) by reducing its brittleness and internal stresses. Further Reading

To soften and relieve strains in any solid material, such as metal or glass, by heating to just below its melting point and then slowly cooling it. This also generally lowers the tensile strength of t [..]

To soften by heating and allowing to cool slowly.

The pairing of complementary DNA or RNA sequences, via hydrogen bonding, to form a double-stranded polynucleotide. Most often used to describe the binding of a short primer or probe.
