2. 6. Study of microstructure development in hypoeutectic grey cast iron

   Author : Ruben Lora; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The avoidance of shrinkage porosity and metal expansion penetration defects as well as the control of the size and number of eutectic colonies and the tensile properties of the casting are issues of major importance in the production of lamellar cast iron. These defects, characteristics and properties are related to the microstructure that develops during solidification. READ MORE

4. 7. A Study On Factor Influencing the Microstructure and Shrinkage Porosity Formation in Compacted Graphite Iron

   Author : Sadaf Vazehrad; Pär Jönsson; Attila Dioszegi; Steve Dawson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CGI; LGI; SGI; Solidification; Microstructure; Shrinkage porosity; Eutectic colony; Microsegregation;

   Abstract : During the last decades, an intensive effort has been dedicated to introduce compacted graphite iron (CGI) for truck engine components as its intermediate graphite morphology provides an increased tensile property compared to lamellar cast iron (LGI) and a better thermal conductivity compared to nodular cast iron (SGI). However, the narrow production technology window in this cast iron grade requires increased technological discipline. READ MORE
