Abstract
Austempered ductile iron castings having primary iron carbides uniformly dispersed throughout an ausferritic matrix, and methods of making the same, are described. The dissolution of the primary iron carbides into the ausferritic matrix during the austempering process is prevented or lessened by altering the chemical composition of the ductile iron, employing a stabilizing agent, by altering the processing parameters of the austempering process, or any combination thereof.
