Ferrous metals include cast iron, steel, and the various steel alloys, The only difference between iron and steel is the carbon content. Cast iron contains more than 2-percent carbon, while steel contains less than 2 percent. An alloy is a substance composed of two or more elements. Therefore, all steels are an alloy of iron and carbon, but the term “alloy steel” normally refers to a steel that...

This thesis deals with the heat evolution during solidification and its relation to the formation of porosity. It intends to improve the current understanding of the formation of porosity in cast materials with special interest in nodular cast iron and the spray forming process. Two different systems, a Fe-based alloy, Cast iron, and a Ni-based alloy, Inconel 625, are examined. The effect on th...

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...
