A RESEARCH ON THE CALCULATION OF GRAPHITIZATION ABILITY OF GRAY CAST IRONS
In this research the relationship between graphitization ability and the carbon equivalent (CE %) of a cast iron have been investigated. The first series of moulds were cast at CE of 3.2% and pouring temperature of 1350°C. The other moulds were cast at different CE% with varying Si content. The graphitization ability( c ) was calculated using the thermodynamics aspects of graphitization and CE%...
متن کاملCast Iron Metallurgy
Cast iron (CI) is one of the oldest materials in commercial use. It has excellent compressive strength and is commonly used for structures that require this property, as well as for water and sewer lines. This article explains CI metallurgy and why the understanding of this metallurgy is key to understanding other ferrous materials and alloys. The composition of cast iron (CI) varies significan...
متن کاملEffect of Chromium and Titanium on Structure and Properties of White Cast Iron
Joint effect of chromium and titanium on structure and properties of hard castings is investigated in present work. It is determined that titanium neutralizes carbide-forming effect of chromium in the investigated concentration intervals. In the presence of titanium, the effect of chromium on hardness of samples is lower as compared to its individual effect. Therefore, addition of only chromium...
متن کاملTribological Behavior of Reinforced and Unreinforced High Chromium Cast Iron
In this paper, the metal matrix composites containing 22 wt % Cr, 2.5 wt % C and 2 to 16 volume percent TiC were processed by solidifying Fe-Cr-Ti-C in which precipitation of titaniumcarbide and chromium carbide occurred. The microstructure and abrasion resistance of in-situ synthesized composites were compared with the unreinforced high chromium white cast iron (HCWCI) containing 22 w. t. % C...
متن کاملGray cast-iron water pipe metallurgy
The results of a metallographic study of grey cast iron water pipes are reported. These pipes had been installed between 1885 and 1973 in eight different water systems. Each pipe had been extracted during scheduled maintenance or failure repairs to provide data for a larger study to produce a methodology for determining the residual life of grey cast iron pipes. This metallographic study was co...
