  • Austempering - Wikipedia

    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.

  • Austempered Ductile Iron - Wikipedia

    Austempered Ductile Iron (ADI) is a form of ductile iron that enjoys high strength and ductility as a result of its microstructure controlled through heat treatment. While conventional ductile iron was discovered in 1943 and the austempering process had been around since the 1930s, the combination of the two technologies was not commercialized until the 1970s.

    BackgroundMechanical PropertiesSpecificationsApplicationsHeat TreatmentThe mechanical properties of ductile iron and ADI are primarily determined by the metal matrix. The matrix in conventional ductile iron is a controlled mixture of pearlite and ferrite.The properties of ADI are due to its unique matrix of acicular ferrite and carbon stabilized austenite; called Ausferrite. The austempering process is neither new nor novel and has been utilised since the 1930’s on cast and wrought steels. The austempering process was first commercially applied to ductile iron i...
