- Swedish truck industry is investigating the possibilityfor implementing the use of Compacted Graphite Iron (CGI) in theirheavy duty diesel engines. Compared to the alloyed gray iron usedtoday, CGI has superior mechanical properties but not as goodmachinability. Another issue that needs to be addressed whenimplementing CGI is the inhomogeneous microstructure when thecast component has different section thicknesses, as in cylinderblocks. Thinner sections results in finer pearlite, in the material, withhigher strength. Therefore an investigation on its influence onmachinability was needed. This paper focuses on the effect thatinterlamellar distance in pearlite has on CGI machinability andmaterial physical properties. The effect of pearlite content andnodularity is also examined. The results showed that interlamellardistance in pearlite did not have as large effect on the materialphysical properties or machinability as pearlite content. The paperalso shows the difficulties of obtaining a homogeneousmicrostructure in inhomogeneous workpieces.
