Austempered Ductile Iron (ADI) is a ferrous, cast material with a high strength-to-weight ratio and good dynamic properties. However, many designers are only vaguely familiar with the savings related to near net shape castings and totally unfamiliar with this material that can compete favorably with steel and aluminum castings, weldments and forgings. This paper will review the design considerations for ADI to help the mechanical designer in his/her material/process selection activity early in the design process.
