Abstract:

White case irons are not normally considered melleable. Recent work at Stanford, however, has demonstrated that these materials can in fact be hot forged, hot rolled and warm rolled. Further, such a series of thermomechanical treatments refines the as-cast structure so as to impart unusual and highly beneficial properties to the cast irons. In particular, the worked, white cast irons are found to be superplastic and there is a great improvement in room temperature properties. This processing procedure may therefore have significant technological applications. Author
