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.

On the Mechanism of Casting Skin Formation in Compacted Graphite Cast Iron
International Journal of Metalcasting, 2009The mechanical properties of ductile iron (DI) and compacted graphite iron (CGI) iron are measured and reported on standard machined specimens (as per ASTM). However, most castings retain most of the as-cast surface. This surface layer (the casting skin) includes both surface and subsurface features.

Creep behavior accompanying oxidation of compacted graphite cast iron
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2018Abstract The creep behavior accompanying oxidation of a compacted graphite cast iron (CGI) containing Cu, Mo and Sn elements was studied at temperatures ranging from 350 °C to 550 °C and creep loads ranging from 40 MPa to 150 MPa. The creep damage was observed using both optical and scanning electron microscopy (SEM).

Comparison of austempering transformation in spheroidal graphite and compacted graphite cast irons
International Journal of Cast Metals Research, 2006AbstractMicrostructure observations and measurements of retained austenite content are reported as a function of austempering time at temperatures of 440, 370, and 300°C after austenitising at 900°C. The results of the experimental investigation indicate that at early stages of austempering (less than ∼8 min), compacted graphite irons usually show ...

Mechanism of bainitic transformation in compacted graphite cast irons
Metallurgical Transactions A, 1990Samples of unalloyed compacted graphite cast iron (CGI) have been thermally treated to obtain a bainitic structure. Heat treatments consisting of various holding times at two different austenitizing temperatures and two different austempering temperatures have been carried out followed by metallographic observations of the resultant structures by ...

General Characteristic of the Ductile and Compacted Graphite Cast Iron
SpringerBriefs in Materials, 2015This section provides basic information about the spheroidal graphite cast iron (SGI) and compacted graphite cast iron (CGI) which belong to the group of high-quality cast iron. The classification of SGI and CGI according to ISO standards, their characteristics and the use of modern types such as ADI or Si–Mo were provided.
