Mechanical properties of compacted graphite cast iron with different microstructures [PDF]
International Journal of Cast Metals Research, 2014 Tensile strength, fracture toughness and impact properties were evaluated in compacted graphite (CG) cast iron with ferritic, pearlitic and ausferritic microstructures. Ultimate tensile strengths for the ferritic and pearlitic samples were 337 and 632 MPa respectively. The austempered samples showed a significant increment in the strength and recording

Fatigue crack growth in compacted and spheroidal graphite cast irons
International Journal of Fatigue, 2020 Abstract The present paper focuses on the fatigue life of a Compacted Graphite cast Iron (CGI) as compared to a Spheroidal Graphite cast Iron (SGI). Fatigue crack growth laws have been determined with digital image correlation. Main difference between the materials is that cracks propagate faster in the CGI than in the SGI.

Study of the solidification structure of compacted graphite cast iron
International Journal of Cast Metals Research, 2016 AbstractThis investigation focuses on the study of the solidification mechanism of compacted graphite cast iron (CGI). The solidification macrostructure was revealed in cast samples using a special technique known as direct austempering after solidification (DAAS). The microstructure was revealed by colour etching.
