Ductile iron is a high-strength cast material. The spherical graphite obtained by inoculation treatment effectively improves the mechanical properties of iron, resulting in higher strength than carbon steel. However, severe corrosion may occur under specific circumstances, especially thermal water pipelines. In this paper, mechanisms at main defective points ductile were investigated using micr...

This article is analyzing the prospects and ways to expand field of applying ductile cast iron-high-strength iron in technology. Ductile occupies a special place among structural materials. With same level mechanical properties, having less specific weight than steel, it provides products comparison with steel. reduces consumption raw materials energy resources manufacture operation machines me...

In this work the predictions based on a theoretical analysis aimed at elucidating of eutectic cell count or nodule counts N were experimentally verified. The experimental work was focused on processing flake graphite and ductile iron under various inoculation conditions in order to achieve various physicochemical states of the experimental melts. In addition, plates of various wall thicknesses,...

The ship is safest when it is in port, but that's not what ships were built for. ABSTRACT Due to coming emission legislations, the temperature is expected to increase in heavy-duty diesel engines, specifically in the hot-end of the exhaust system affecting components, such as exhaust-and turbo manifolds. Since the current material in the turbo manifold, a ductile cast iron named SiMo51, is oper...

Due to coming emission legislations, the temperature is expected to increase in heavy-duty diesel engines, specifically in the hot-end of the exhaust system affecting components, such as exhaustand turbo manifolds. Since the current material in the turbo manifold, a ductile cast iron named SiMo51, is operating close to its limits there is a need for material development in order to maintain a h...

The industrial demand for increased component performance with concurrent reductions in component weight, development times and verifications using physical prototypes drives the need to use the full potential of casting and Finite Element Method (FEM) simulations to correctly predict the mechanical behavior of cast components in service. The mechanical behavior of the component is determined b...

In this research the role of alloying elements on the microstructure and mechanical properties of an as cast and hot rolled high strength low alloy (HSLA) steel was studied. Different compositions with different amount of copper in the presence of nickel, hot rolled and quenched in oil. Tensile test, hardness test, scanning electron microscope (SEM) and optical microscope (OM) were used to eval...
