Effect of Cooling Rate and of Titanium Additionson the Microstructure of Thin-Walled Compacted Iron Castings

This article addresses the effect of cooling rate and of titanium additions on the exhibited microstructure of thin-walled compacted graphite iron (TWCI) castings as determined by changing molding media, section size and Ferro Titanium. Various molding materials were employed (silica sand and insula...
