Austempering  

Definisjon

  • 1. Austempering is a heat treating process for medium-to-high carbon ferrous metals which produces a metallurgical structure called bainite. It is used to increase strength, toughness, and reduce distortion. Parts are heated to the hardening temperature, then cooled rapidly enough to a temperature above the martensite start (Ms) temperature and held for a time sufficient to produce the desired bainite microstructure. (https://www.bodycote.com). 2. Austempering is heat treatment that is applied to ferrous metals, most notably steel and ductile iron. In steel it produces a bainite microstructure whereas in cast irons it produces a structure of acicular ferrite and high carbon, stabilized austenite known as ausferrite. It is primarily used to improve mechanical properties or reduce / eliminate distortion. (Wikipedia). 3. ‘Austempering’ is the process of heat treatment where the steel is heated to austenitizing temperature, held there for sufficient period of time to produce homogeneous austenite.
