Age Strengthening of Cast Irons: Review of Research and Literature
Since 1997, AFS has supported a number of studies to improve the understanding of the age strengthening in gray cast iron. This has resulted in a series of publications and presentations that address aging behavior in a piecemeal fashion. The purpose of this paper is to knit together those pieces in the context of the literature on age strengthening in ferrous alloys. The conclusion reached from these studies is that the age strengthening is a nitride precipitation process described by Avrami-Johnson-Mehl kinetics. Keywords: cast iron, age strengthening, aging, nitrides, machinability
