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...

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...

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...

Hypereutectic aluminum silicon alloys are mainly used in cast form in important components like pistons, cylinder liners, rocker arms, air conditioner compressors, brake drums, engine blocks, etc. These have inherent advantages of being high wear resistance, high strength to weight ratio, high corrosion resistance, good cast performance, high thermal conductivity, good weldability, etc. The inf...

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...
