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. This treatment is an important part in the processing of steel. Discovered by Benjamin, the process is now a critical part of steel infrastructure and is used at quantities upwards of 100,000 tons daily.
