The initiation and propagation of thermal fatigue cracks in gray cast iron vemicular graphite were investigated by Uddeholm method to reveal the complex behaviors iron. Differences observed analyzed. It is found that differences are related combination morphology oxidization matrix. More oxidized matrix due its large specific surface area. brittle facilitates microcracks along layer. By contras...

The reason of this study is low cycle failure of cast iron cylinder head during the E5 standard durability test. The goal of the present investigation is durability test simulation and low cycle fatigue life evaluation of cast iron cylinder head. With uncouple structural analysis, preloads, thermal and mechanical load and boundary conditions are prescribed to finite element model of the cylinde...

in this paper, the reasons of damage water pumps parts of the air compressor cooling system were studied. to reach this goal, the works like preparing metallographic samples, evaluation of structure, investigation of mechanical properties, the alloy parts detection and chemical analysis of deposit and corrosion products collected from the parts were performed. according to studies and results o...

The remote field effect is an electromagnetic method for inspecting pipes and tubing. It has recently been commercialised as a technique for inspecting gray cast iron and ductile iron water mains. However, commercial tools provide information on pits depths in the pipe and overall wall loss. Models of the mechanical behaviour of cast iron pipe also require information on pit width and length. T...

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...
