To the design engineer, hardness often means an easily measured quantity which indicates something about the strength and heat treatment of the metal. Austempered ductile iron (ADI) is an alloyed and heat treated ductile cast iron which has a good combination of mechanical properties. This paper describes a neural network model created within a Bayesian framework using published data. The model expresses the hardness as a function of a large number of compositional and processing variables. The model is available on the world-wide web.
