On the Mechanism of Casting Skin Formation in Compacted Graphite Cast Iron

International Journal of Metalcasting, 2009
The 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.

Comparison of austempering transformation in spheroidal graphite and compacted graphite cast irons

International Journal of Cast Metals Research, 2006
AbstractMicrostructure 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, 1990
Samples 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 ...

Interaction of boron suboxide with compacted graphite cast iron

Ceramics International, 2011
Abstract The chemical interaction of boron suboxide (B 6 O) with compacted graphite cast iron (CGI) was investigated using static interaction diffusion couples between B 6 O and CGI at 700 °C, 900 °C and 1100 °C for 1 h. This interaction offers the possibility to evaluate the potential of B 6 O as a cutting tool.

Compacted graphite iron: Cast iron makes a comeback

JOM, 1994
Although compacted graphite iron has been known for more than four decades, the absence of a reliable mass-production technique has resulted in relatively little effort to exploit its operational benefits. However, a proven on-line process control technology developed by SinterCast allows for series production of complex components in high-quality CGI.
