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

A Case Study on the Casting Skin Phenomena in Compacted Graphite Iron Cast Components [PDF]
International Journal of MetalsIn sand casting, the surface microstructure often differs from the bulk microstructure due to mold–metal interactions. In nodular and compacted graphite iron, these interactions manifest mostly by a variation in graphite morphology, often attributed to ...

Using a neural network model to evaluate the mechanical and tribological properties of vermicular cast iron based on hardness [PDF]
Heliyon, 2023 Measuring the tensile strength, wear resistance, and impact strength of metals, particularly cast iron, is complex and more expensive than performing hardness tests.

Extrema of micro-hardness in fully pearlitic compacted graphite cast iron
International Journal of Cast Metals Research, 2020 For improving the mechanical strength of cast irons, a fully pearlitic matrix is sought by alloying with tin, copper and manganese. This applies in particular to the compacted graphite irons considered here. While average macro- and micro-hardness values

OXYGEN POTENTIAL VALUES TO PRODUCE COMPACTED GRAPHITE CAST IRON
Canadian Metallurgical Quarterly, 2008 AbstractCompacted graphite cast iron (CGI) is a potential alternative to lightweight alloys. It is accepted that CGI can effectively reduce the automobile total weight by virtue of its high strength and its high thermal conductivity giving an opportunity to designers to design components with thinner sections. However, the successful casting process to

Cutting Performance of Low Stress Thick TiAlN PVD Coatings during Machining of Compacted Graphite Cast Iron (CGI) [PDF]
, 2018 A new family of physical vapor deposited (PVD) coatings is presented in this paper. These coatings are deposited by a superfine cathode (SFC) using the arc method. They combine a smooth surface, high hardness, and low residual stresses.

Effect of Cooling Rate on the Eutectoid Transformation in Compacted Graphite Cast Iron [PDF]
Materials Science Forum, 2018 Differential thermal analysis has been used to characterize the effect of cooling rate on the eutectoid transformation of a compacted graphite iron. The samples were machined out from an as-cast thermal cup, austenitized at 950°C and then cooled to room ...

The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2014 In compacted/vermicular graphite cast iron production, inoculation is applied to limit the formation of carbides, but usually this treatment also promotes nodular graphite with improved nodularity.
