2. 1. Compacted graphite iron : On solidification phenomena related to shrinkage defects

   Author : Björn Domeij; Attila Diószegi; Babette Tonn; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compacted graphite iron; Spheroidal graphite iron; Solidification; Microsegregation; Porosity; Kompaktgrafitjärn; segjärn; stelning; mikrosegregation; porositet;

   Abstract : An improved understanding of solidification of compacted graphite iron (CGI) is necessary to predict shrinkage related casting defects. Spheroidal graphite is not only found in ductile iron (SGI) but usually also in CGI, but its characteristics and role in this material is less understood. READ MORE

4. 2. Characterization of factors interacting in CGI machining : machinability - material microstructure - material physical properties

   Author : Anders Berglund; Cornel Mihai Nicolescu; Tero Stjernstoft; KTH; []

   Abstract : The Swedish truck industry is forced to find new material solutions to achieve lighter engines with increased strength. Customers and new environmental regulations demand both higher specific power and more environmentally friendly trucks, and this places a rising pressure on the manufactures. READ MORE

5. 3. Microstructure Formation and Mechanical Properties in Compacted Graphite Iron

   Author : Mathias König; Ingvar L. Svensson; Magnus Wessén; Torsten Sjögren; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; CGI; Microstructure formation; Mechanical properties;

   Abstract : Compacted graphite iron is rapidly becoming an attractive alternative for engine applications in the automotive industry. The improved process control now available that allows CGI components to be cast in a reproducible and reliable way has been the driving force for this development. READ MORE

6. 4. On the solidification of compacted and spheroidal graphite irons

   Author : Björn Domeij; Attila Diószegi; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compacted graphite iron; Spheroidal graphite iron; Solidification; Microsegregation; Kompaktgrafitjärn; segjärn; stelning; mikrosegregation;

   Abstract : A good understanding of the solidification process of a cast material is essential to understand how the combination of alloy composition and the casting process variables combines into the solid cast component and its performance. The wrong combination may result in poor performance or casting defects. READ MORE

7. 5. Microstructure Formation During Solidification and Solid State Transformation in Compacted Graphite Iron

   Author : Mathias König; Magnus Wessén; Ingvar L. Svensson; Jorge Sikora; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast Iron; CGI; Microstructure Formation; Mechanical Properties; Modelling; Solidification; Solid State Transformation;

   Abstract : Compacted graphite iron (CGI) is rapidly becoming an attractive alternative material for engine components in the automotive industry, replacing lamellar graphite iron (LGI) in applications where high mechanical strength is desired. However, the gain in mechanical strength comes with a cost; thermal conductivity, process control and machining are three areas that are more challenging for CGI. READ MORE
