Cast iron is a very common and useful metal alloy, characterized by its high carbon content (>4%) in the allotropic state of graphite. The correct shape distribution graphite are essential for ensuring that material has right properties. present investigation examines metallurgical mechanical characterization spheroidal (nodular) cast iron, an alloy derives name excellent properties from pre...

In the paper, the author has represented a thermodynamic analysis of a crucible reaction, which takes place in crucible induction furnaces. The author has suggested a diagram of a crucible reaction that took into account partial pressure and activity of the components participating in the process. The author has defined more exactly what effect the elements usually present in cast iron (Mn, S, ...

In order to assess the remaining life of cast iron assets in the water sector, an understanding of their fracture and fatigue characteristics is necessary. The present work is concerned with the toughness and Paris crack growth behaviour of cast iron materials with a range of microstructures, taken from trunk mains currently in service. When considered with other data from the literature, the r...

In the present investigation the effect of the substrate dilution on room and high temperature (550 and 700 oC) tribological behaviour of nickel based hardfaced coating deposited by plasma transferred arc onto a grey cast iron was investigated and compared to the uncoated grey cast iron. At room temperature, the wear loss of coatings was independent of the substrate dilution and similar to the ...

Human civilization has evolved from the Stone Age, through the Bronze Age to reach the Iron Age around 1500 B.C. There are many to contend that today we are living in the age of engineered materials, yet the importance of iron castings continues to support the thesis that we are still in the Iron Age. Cast iron, the first man-made composite, is at least 2500 years old. It remains the most impor...

This thesis concerns grey cast iron gas pipelines in Amsterdam managed by the regional gas and electricity grid operator Liander. Due to brittle nature and aging process of grey cast iron, probability of explosion in this type of pipelines seems to be increasing. A model for the gas explosion probability is proposed. Multiple factors are taken into consideration, including pipe’s age, length, w...
