Creep behavior accompanying oxidation of compacted graphite cast iron
Materials Science and Engineering: A, 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).

Graphite Phase Characteristics in Compacted/Vermicular Graphite Cast Iron Inoculated in the Mould
Advanced Materials Research, 2015The objective of this research paper is to examine the effects of adding an oxy-sulphide inoculant enhancer alloy [OS-IE = S,O,Al,Mg-CaSi alloy] to a conventional CaBa-FeSi alloy and to examine the graphite phase characteristics in these irons, as affected by different in the mould inoculants, for resin sand mould castings. The surface layer of all the

Thermophysical Properties of Thin Walled Compacted Graphite Iron Castings
2015The thermal conductivity, diffusivity and specific heat were investigated in thin walled compacted graphite iron castings. The research was conducted for thin-walled iron castings with a 3-mm wall thickness. This study addresses the effect of cooling rate and of titanium additions on the exhibited microstructure and thermophysical parameters of thin ...

Influence of alloying additions on austempering kinetics of compacted graphite cast iron
Materials Science and Technology, 1998AbstractAustempering kinetic measurements are reported for a compacted graphite iron of composition Fe-3.4C-3.5Si-0.25Mn- 0.5Mo-0.5Ni (wt-%) for an austempering temperature of 375°C and austenitising temperatures of 890, 900, and 940°C. The measurements show that increasing the Si content accelerates the stage I reaction and delays the stage II ...
