Annealing may refer to:
  • Annealing (metallurgy)
    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. It is a process that produces conditions by heating to above the recrystallization temperature, maintaining a suitable temperature, and...

    , a heat treatment that alters the microstructure of a material causing changes in properties such as strength and hardness and ductility
  • Annealing (glass)
    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. Glass which has not been annealed is liable to crack or shatter when subjected to a relatively small temperature change...

    , heating a piece of glass to remove stress
  • Annealing (biology), DNA or RNA pairing by hydrogen bonds to a complementary sequence, forming a double-stranded polynucleotide
  • Simulated annealing
    Simulated annealing
    Simulated annealing is a generic probabilistic metaheuristic for the global optimization problem of locating a good approximation to the global optimum of a given function in a large search space. It is often used when the search space is discrete...

    , a technique for searching for a solution in a space otherwise too large for "ordinary" search methods to yield results
  • Quantum annealing
    Quantum annealing
    In mathematics and applications, quantum annealing is a general method for finding the global minimum of a given objective function over a given set of candidate solutions , by a process analogous to quantum fluctuations...

    , a method for finding solutions to combinatorial optimisation problems and ground states of glassy systems using quantum fluctuations
