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

Thermal dependence of austempering transformation kinetics of compacted graphite cast iron [PDF]
Metallurgical and Materials Transactions A, 2001 The evolution of the relative fraction of high-carbon austenite with austempering time and temperature was analyzed in a compacted graphite (CG) cast iron (average composition, in wt pct: 3.40C, 2.8Si, 0.8Mn, 0.04Cu, 0.01P, and 0.02S) at five different austempering temperatures between 573 and 673 K. Samples were characterized by Mossbauer spectroscopy,

Solidification and Room Temperature Microstructure of a Fully Pearlitic Compacted Graphite Cast Iron [PDF]
Transactions of the Indian Institute of Metals, 2018 Compacted graphite cast irons are rapidly developing for they have better mechanical properties than lamellar graphite cast irons and present less porosity than spheroidal graphite cast irons. For many applications, an as-cast fully pearlitic matrix would be desired which can hardly be achieved when graphite is compacted.

Constructive Improvements in the In-Ladle Treatments - A Comparative Industrial Study [PDF]
Tehnički Glasnik, 2022 Nodular gray cast iron having properties superior to conventional gray cast iron can be produced by treating the molten iron so that, when cast, the graphite will be compacted rather than in flake form.

Study of the solidification structure of compacted graphite cast iron [PDF]
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.

Abrasive Wear of Compacted Graphite Cast Iron with Added Tin [PDF]
Metallography, Microstructure, and Analysis, 2018 The abrasive wear behavior of traditional compacted graphite cast iron (CGI) and compacted graphite cast iron with 0.1% tin addition (CGI–Sn) is studied using a pin-on-disk tribometer. The microstructures of these two CGIs were observed by optical microscopy and scanning electron microscopy.
