摘　　要：Spheroidal Graphite Cast Iron, SG iron in short, refers to the cast iron in which graphite precipitates as spheroidal shape during solidification of liquid iron. The graphite in common commercial cast iron can only be changed from flake to spheroidal shape by spheroidising treatment. Since spheroidal graphite reduces the cutting effect of stress concentration, the metal matrix strength of SG iron can be applied around 70% - 90%, thus the mechanical property of SG iron is significantly superior to other cast irons; even the tensile strength of SG iron is higher than that carbon steel.Note:This book consists of five sections:Chapter 1 Introduction,Chapter 2 Grey Iron,Chapter 3 Spheroidal Graphite Cast Iron,Chapter 4 Vermicular Cast Iron,and Chapter 5 White Cast Iron.CHINA FOUNDRY publishes this book in several parts serially,starting from the first issue of 2009.
