AUSTEMPERED IRONS Austempering can be applied to ductile and gray ironIncreased tensile s castings to produce beneficial properties relevant toaustempering gray iron at various temperatures. numerous appliions. In the case of gears and shafts,
The development of austempered ductile iron (ADI) is a major achievement in cast iron technology. The austempering heat treatment enables the ductile cast iron containing mainly strong bainitic ferrite and ductile carbon-enriched austenite, with some martensite transforms from austenite during cooling down to room temperature.
iii ABSTRACT Austempered Ductile Iron (ADI) is a relatively new material with the highest hardness and strength of any material in the cast iron family. Through the unique heat treatment - austempering, the “ausferrite” microstructure of ferrite and carbon-stabilized

16/10/2019· Carbidic Austempered Ductile Iron is a recent, special type of austempered ductile iron (ADI) containing carbides in its ausferritic matrix. The CADI is a type of cast iron that can be produced by subjecting carbidic ductile iron to austempering mode of heat treatment processes at different temperatures and time.
