INVESTIGATION OF DUCTILE IRON IN MOLD

INVESTIGATION OF DUCTILE IRON IN MOLD

Ductile iron was first developed in 1943 and it is widely used in automotive industry. The difference between cast iron and ductile iron is due to the presence of spheroid graphite in the matrix of ductile iron which is not found in brittle cast iron. Ductile iron possesses higher ductility and tensile strength than in cast iron.

An investigation of the mechanical damping of ductile iron

An investigation of the mechanical damping of ductile iron

Ductile iron has been suggested as a candidate material for a number of practical applications, including turbine castings, automotive components, and transportation and storage casks for hazardous and radioactive materials. The applications require the enhanced ductility resulting from the presence of spherical graphite nodules in the ductile ferrite iron matrix.

Experimental Investigation on Corrosion of Cast Iron Pipes

Experimental Investigation on Corrosion of Cast Iron Pipes

It is well known that corrosion is the predominant mechanism for the deterioration of cast iron pipes, leading to the reduction of pipe capacity and ultimate collapse of the pipes. In order to assess the remaining service life of corroded cast iron pipes, it is imperative to understand the mechanisms of corrosion over a long term and to develop models for pipe deterioration.
