Anneal may refer to:

  • Annealing (metallurgy), a heat treatment wherein the microstructure of a material is altered, causing changes in its properties such as strength and hardness.
  • Annealing (glass), heating a piece of glass until its temperature reaches a stress-relief point.
  • Annealing (biology), in genetics, DNA or RNA pairing by hydrogen bonds to a complementary sequence, forming a double-stranded polynucleotide.
  • Simulated annealing, a technique for searching for a solution in a space otherwise too large for "ordinary" search methods to yield results.
  • Information annealing or knowledge annealing, in library and information science, is a network-based information system or body of knowledge in which all users of the system are permitted to change the system at will.


Go to www.technologystudent.com/equip1/heat3.htm Annealing, in metallurgy and materials science, is a heat treatment wherein the microstructure of a material is altered, causing changes in its properties such as strength and hardness. ... Annealing, in glassblowing and lampworking, is heating a piece of glass until its temperature reaches a stress-relief point, that is, a temperature at which the glass is still too hard to deform, but is soft enough for internal stresses to ease. ... Annealing, in genetics, means for DNA or RNA to pair by hydrogen bonds to a complementary sequence, forming a double-stranded polynucleotide. ... Simulated annealing (SA) is a generic probabilistic meta-algorithm for the global optimization problem, namely locating a good approximation to the global optimum of a given function in a large search space. ... Information annealing or knowledge annealing, in library and information science, is a network-based information system or body of knowledge in which all users of the system are permitted to change the system at will. ...


This will show you a demonstration of annealing with funny pictures. Have fun guys...


When metals are heated to a very hot temperature(not melted), and then are cooled slowly in air, they become annealed, and weaker.


When you cool metals slowly, they become weaker, and when you cool them quickly, the become stronger. Not much else happens, except for density changes.


Np for the help,


Ryan <------ This man is an idiot, but his info is true.... (Np for help, What the????)

Annealing (metallurgy), a heat treatment wherein the microstructure of a material is altered, causing changes in its properties such as strength and hardness.
Annealing, in glassblowing and lampworking, is heating a piece of glass until its temperature reaches a stress-relief point, that is, a temperature at which the glass is still too hard to deform, but is soft enough for internal stresses to ease.
The term is often used to describe the binding of a DNA probe, or the binding of a primer to a DNA strand during a polymerase chain reaction (PCR).
Simulated annealing - definition of Simulated annealing in Encyclopedia (1450 words)
Simulated annealing (SA) is a generic probabilistic heuristic approach for the global optimization problem, namely locating a good approximation to the global optimum of a given function in a large search space.
The name and inspiration come from annealing in metallurgy, a technique involving heating and controlled cooling of a material to increase the size of its crystals and reduce their defects.
In the simulated annealing (SA) method, each point s of the search space is compared to a state of some physical system, and the function E(s) to be minimized is interpreted as the internal energy of the system in that state.
