Effects Of Refrigeration And Cryogenic Treatments On Austempered Ductile Iron, Gerard R. Thiel Jan 1996

Effects Of Refrigeration And Cryogenic Treatments On Austempered Ductile Iron, Gerard R. Thiel

Dissertations and Theses @ UNI

Low temperature treatment, as a method of improving mechanical properties of metals, has been studied and used for well over 60 years. Until recently these treatments have been limited to hardness and wear improvements of high alloy irons and steels. The purpose of this research is to determine the effects of refrigeration and cryogenic treatments on the mechanical properties, including hardness and tensile strength of austempered ductile iron.

This research included the production of a high strength ductile iron of low alloy content capable of being used in either the as cast, conventionally heat treated or austempered condition. Refrigeration and …
