Ausforming

Ausforming also known as Low and High temperature thermomechanical treatments is a method used to increase the hardness and toughness of an alloy by simultaneously tempering, rapid cooling, deforming and quenching to change its shape and refine the microstructure.^[1] This treatment is an important part in the processing of steel.^[2]

Iron and steel production

Iron production
(Ironworks)

Smelting	Bloomery (produces sponge iron) Blast furnace (produces pig iron) Cold blast Hot blast Anthracite iron Direct reduced iron
Secondary	Wrought iron (via Finery forge or Reverberatory Puddling Furnace) Cast iron (via Cupola furnace or Induction furnace)

Steelmaking
(Steel mill)

Primary (Pre-1850)	Pattern welding (Damascus steel) Crucible steel Tatara furnace Cementation process
Primary (Post-1850)	Bessemer process Open hearth furnace Electric arc furnace Basic oxygen process
Secondary	Electro-slag remelting Vacuum arc remelting Argon oxygen decarburization
