annealed

[əˈniːld ]

Definition

Context #1 | Verb

material science

Annealing is a heat treatment process that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it easier to work with. This process involves heating the material to a specific temperature, holding it there for a certain period, and then cooling it down, usually in air. It is commonly used in the processing of metals to relieve internal stresses, refine the grain structure, and improve machinability. The annealing process can also enhance the electrical conductivity of certain materials.

Synonyms

heat treatment, tempering.

Examples of usage

  • The metal was annealed to improve its ductility.
  • After the annealing process, the steel became easier to cut.
  • Annealing glass can create a more uniform texture.
  • The technician carefully monitored the annealing temperature.

Interesting Facts

Science

  • The process involves heating the metal to a specific temperature to relieve internal stresses and improve its workability.
  • Annealing alters the microstructure of metals, making them less brittle and enhancing their ductility.
  • Different metals require different annealing temperatures and times, ranging from a few hundred to over a thousand degrees Celsius.

Industry

  • It is a critical process in manufacturing, especially in the production of wires, sheets, and tubes.
  • Annealed metal is commonly found in kitchen appliances, transport, and construction materials due to its improved properties.

History

  • The practice of annealing goes back to ancient times, with evidence found in metalworking artifacts from Mesopotamia.
  • Blacksmiths have historically used this technique to shape and refine iron and steel for tools and weapons.

Pop Culture

  • This term often appears in metaphors related to personal growth, symbolizing the idea of becoming stronger and more resilient after facing difficulties.
  • In literature and film, characters might be described as 'annealed' when they undergo significant emotional or physical trials and emerge stronger.

Origin of 'annealed'

Main points about word origin

  • The term comes from the Latin word 'anhelare,' meaning 'to breathe.' It implies a transformation through a process.
  • Initially used in English around the late 1500s, referring to physical changes in materials, particularly metals.

The term 'annealed' traces back to the Old French word 'anillier', which means to 'to heat' or 'to temper'. This, in turn, comes from the Latin word 'lignum', meaning 'wood', linking the process to traditional methods of heating metals with wood fuel. The process of annealing has been known and used since ancient times, primarily in metallurgy and glassworks, as a means to strengthen materials and make them easier to manipulate. Over time, it has evolved with advancements in technology and understanding of material science, finding applications beyond just metals to include polymers and ceramics. The modern industrial processes of annealing are now critical in various manufacturing sectors, highlighting the historical importance of this technique.
