Daeth Ford Motor Company Ltd., England U. Reuter and H. Schulz PTW, University of Darmstadt, Germany Copyright © 2001 Society of Automotive Engineers, Inc. ABSTRACT widespread acceptance as a cylinder block material, its machinability should approach that of conventional gray The influence of graphite shape, pearlite content and cast iron. chemical composition have been investigated to determine their effect on the machinability of compacted In general, the three available avenues for optimizing the graphite iron (CGI) . In the comparison to gray iron, the machinability of CGI include: improving the robustness reduced sulfur content of CGI prevents the beneficial of the
