A full annealing typically results in the second most ductile state a metal can assume for metal alloy. Its purpose is to originate a uniform and stable microstructure that most closely resembles the metal's phase diagram equilibrium microstructure, thus letting the metal attain relatively low levels of hardness, yield strength and ultimate ...
Solvent vapor annealing (SVA) is a widely used technique for controlling the morphology and ordering of block copolymer (BCP) films. [1] [2] [3] By controlling the block ratio (f = NA/N), spheres, cylinders, gyroids, and lamellae structures can be generated by forming a swollen and mobile layer of thin-film from added solvent vapor to facilitate the self-assembly of the polymer blocks.

Annealing may refer to: Annealing (biology), in genetics; Annealing (glass), heating a piece of glass to remove stress; Annealing (materials science), a heat treatment that alters the microstructure of a material; Quantum annealing, a method for solving combinatorial optimisation problems and ground states of glassy systems
Production of galvannealed sheet steel begins with hot dip galvanization of sheet steel. After passing through the galvanizing zinc bath the sheet steel passes through air knives to remove excess zinc, and is then heated in an annealing furnace for several seconds causing iron and zinc layers to diffuse into one another causing the formation of zinc-iron alloy layers at the surface.
Consolidated Engineering Company Archived 2013-11-05 at the Wayback Machine Annealing furnaces cover a broad range of Steel and Aluminum applications including tempering, normalizing, and aging, and similar automated loading, unloading and natural or forced cooling is possible with roller hearth, tip-up or batch arrangements.
Passivation, or thermal annealing, of the interface limits hole/electron recombination, removes dangling bonds, and reduces vacancies and dislocations at grain boundaries. Annealing typically involves heating the wafer and saturating the chamber with a gas or water vapor that can then be incorporated into the film.
Annealing is a process of slowly cooling hot glass objects after they have been formed, to relieve residual internal stresses introduced during manufacture. Especially for smaller, simpler objects, annealing may be incidental to the process of manufacture, but in larger or more complex products it commonly demands a special process of annealing in a temperature-controlled kiln known as a lehr.
