Occurrence and effect of casting skin in compacted graphite iron

International Journal of Cast Metals Research, 2016
Most iron castings retain their as cast surfaces because of their geometric complexity and to minimise the machining costs. However, the mechanical properties that are documented in standards (i.e. ASTM) are tested on fully machined test bars. Therefore, the effect of the as cast surface and subsurface features (commonly referred as ‘casting skin’) on ...

Trace Elements in Nodular and Compacted Graphite in Cast Iron

Cast Metals, 1989
AbstractSecondary Ion Mass Spectrometry (SIMS) was used to qualitatively analyse the distribution of trace solutes in nodules, compacted graphite (CG) particles, and the surrounding matrix in Mg-treated cast iron. In both nodular- and compacted-graphite cast iron, Mg was clearly observed to be present in the graphite particles.

Welding consumable research for compacted graphite cast iron

Journal of Materials Engineering, 1991
Research has developed a new consumable material for gas welding of compacted graphite (CG) cast iron. The effects of C, Si, RE (rare earth), Ti, Al and weld cooling rate on graphite and matrix structure of compacted graphite cast iron welds have been studied. The optimum C, Si, RE and Ti contents of the weld metal were determined.

The Use of Compacted-graphite Cast Iron Returns containing Titanium and Aluminium in Production of Nodular- and Compacted-graphite Irons—Is it a Problem?

Cast Metals, 1989
As production of compacted-graphite irons (CG irons) has continued to rise, the use of denodularising (antispheroidising) elements (Ti, Al, Sb, Sn, etc) has led to the build-up of these deleterious...

Metallographic structure of bainitic compacted graphite cast irons

Materials Characterization, 1991
Abstract The microstructural characteristics of austempered unalloyed compacted graphite cast irons have been studied. The material was subjected to a variety of bainitic treatments based on four different combinations of austenitizing and austempering temperatures, plus various periods of time at the temper temperature.

Graphite Phase Characteristics in Compacted/Vermicular Graphite Cast Iron Inoculated in the Mould

Advanced Materials Research, 2015
The 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

High strength high toughness compacted graphite cast iron

Materials Science and Technology, 1995
AbstractIn the present paper, heat treatments were used to obtain upper and lower bainitic compacted graphite cast irons. The effects of the percentage of compacted graphite, the matrix structure, and the specimen thickness on the mechanical properties, fracture toughness, and fatigue crack growth rate of the irons were evaluated.

Fracture mechanics behaviour of austenitic compacted graphite cast iron

Journal of Materials Science, 1996
The fracture mechanics behaviour of high-nickel austenitic compacted graphite cast iron was studied and the effects of graphite morphology, alloying elements and specimen thickness on the mechanical properties, plane stress fracture toughness, and fatigue crack growth rate were evaluated. It was found that the graphite morphology, i.e.
