anneal

Etymology: AS, aelan, to burn

1 to temper metals, glass, or other materials by controlled heating and cooling to make them more malleable and ductile.

2 to cause the interaction of two separate strands of nucleic acid to form a duplex molecule, often by using a related technique of controlled heating and cooling.

anneal [ah-nēl´]

1. to heat a material, such as glass or metal, followed by controlled cooling to remove internal stresses and induce a desired degree of toughness, temper, or softness of the material.

2. to homogenize an amalgam alloy ingot by heating it in an oven.

3. to heat a material, such as gold foil, to volatilize and drive off impurities from its surface, and to increase its cohesive properties.

anneal (anēl´),

n (homogenizing heat treatment, softening heat treatment), the softening of a metal by controlled heating and cooling.

anneal foil,

n a process of subjecting noncohesive foil to heat to volatilize a protective gaseous coating on its surface, thus leaving the surface clean, making it cohesive.

anneal glass,

n a process of regulated heating and subsequent cooling to remove strain hardening or work hardening of glass.

anneal metal,

n a process of regulated heating and subsequent cooling to remove strain hardening or work hardening of metal.
