anneals, 3rd person singular present; annealed, past participle; annealing, present participle; annealed, past tense;
  1. Heat (metal or glass) and allow it to cool slowly, in order to remove internal stresses and toughen it

  2. Recombine (DNA) in the double-stranded form following separation by heat

  3. (of DNA) Undergo this process

  1. bring to a desired consistency, texture, or hardness by a process of gradually heating and cooling; "temper glass"
  2. (annealing) hardening something by heat treatment
  3. (Annealing (glass)) Annealing is a process of slowly cooling glass to relieve internal stresses after it was formed. The process may be carried out in a temperature-controlled kiln known as a Lehr. ...
  4. (Annealing (metallurgy)) Annealing, in metallurgy and materials science, is a heat treatment wherein a material is altered, causing changes in its properties such as strength and hardness. ...
  5. (Annealing (nucleic acid)) Nucleic acid thermodynamics is the study of the thermodynamics of nucleic acid molecules, or how temperature affects nucleic acid structure. ...
  6. To subject to great heat, and then cool slowly for the purpose of rendering less brittle; to temper; to toughen; To strengthen or harden
  7. (annealing) The act of heating solid metal or glass to high temperatures and cooling it slowly so that its particles arrange into a defined lattice
  8. (Annealed) To subject (glass or metal) to a process of heating and cooling in order to toughen and reduce brittleness.
  9. (Annealed) The condition of a fastener when it has been heated then cooled to make it soft or less brittle.
  10. (Annealed) Softest possible state of any material.
  11. (Annealing) Heating and cooling a metal slowly to relieve internal stress.
  12. (Annealing) Heating above the critical or recrystallization temperature, then controlled cooling of metal, glass, or other materials to eliminate the effects of cold-working, relieve internal stresses, or improve strength, ductility, or other properties.
  13. (Annealing) The heating (and cooling) of a die or planchet to soften the metal before preparation of the die or striking of the coin.
  14. (Annealing) full-A heat-treating operation wherein metal is heated to a temperature above its critical range, held at the temperature long enough to allow full recrystallization, then slowly cooled through the critical range. ...
  15. (Annealing) Heating to and holding at a suitable temperature and then cooling at a suitable rate, for such purposes as reducing hardness, improving machinability, facilitating cold working, producing a desired microstructure, or obtaining desired mechanical, physical, or other properties. ...
  16. (Annealing) A process of holding a material at a temperature near, but below, its melting point. The objective of annealing is to permit stress relaxation without distortion of shape. It is often used on injection molded articles to relieve stresses set up by flow in the mold.
  17. (Annealing) A process involving high-temperature heating and cooling of cold rolled steel substrate to make it softer and more formable.
  18. (annealing) heating blanks (planchets) in a furnace that softens the metal.
  19. (Annealing) Refers to the heating and controlled cooling of steel for the purpose of removing stresses, softening, refining its structure or changing its ductility.
  20. (annealing) The process of formation of double-stranded DNA from single-stranded DNA; compare with hybridization.
  21. (Annealing) the pairing of complementary single strands of DNA to form a double helix.
  22. (Annealing) Heat treatment that alters the microstructure of a material, changing properties such as strength, hardness or ductility.
  23. (Annealing) is a heat treatment applied to metals, its principal effects being the softening of previous cold working through re-crystallization, relief of internal stress, and the homogenization of composition. ...
  24. (Annealing) A softening treatment consisting of the heating carbon or alloy steel to an appropriate temperature, holding at the temperature for a proper period of time and slowly cooling to room temperature.
  25. (annealing) to make less brittle by heating then cooling (as with glass or steel)
