Abstract

The effects of varying carbon content and ferrite grain size on the tensile flow stress of ferritic compacted graphite cast iron from room temperature to 773 K are investigated in this study. The tensile flow stress of ferritic compacted graphite cast iron is affected by the triaxial stress field developed in the matrix between graphite particles and ferrite grain size. The flow stress of this material is described by the equation σ = (1 - k1Vg) (σ0 + k2df 1 2) where Vg is the graphite volume fraction and df the ferrite grain size.
