... Cast Iron This type of cast iron is obtained by adding a small amount of magnesium (0.1-0.8%) to the molten metal. The addition of magnesium causes the ...

Grey cast irons are softer with a microstructure of graphite in transformed-austenite and cementite matrix. The graphite flakes, which are rosettes in three ...
Cast irons typically contain 2-4 wt% of carbon with a high silicon concentrations and a greater concentration of impurities than steels. The carbon equivalent (CE) of a cast iron helps to distinguish the grey irons which cool into a microstructure containing graphite and and the white irons where the carbon is present mainly as cementite. The carbon equivalent is defined as:

Nodular Cast Iron is obtained by adding magnesium just before casting. This encourages the graphite to form spheres or nodules. Ductile iron consists of ...

The 4 types of cast iron include: grey, white, malleable and ductile cast iron. Different processing methods can be used to each type.

Nodular cast iron shows higher strength and ductility than grey cast iron of similar composition. Inoculation of grey cast irons is widely practised and ...
The aim of this paper is to demonstrate the capability of ultrasonic techniques in the assessment of the structure and properties of ductile cast irons, and also contribute to the database concerning the use of ultrasonic velocity and attenuation measurements for quality control. In the experiments, cast iron specimens with different nodularity percentages (0, 50 and 90%) were cast by the addition of different amounts of alloys to the melt, and then various heat treatments were applied. Ultrasonic velocity and apparent attenuation measurements were carried out on the as-cast and heat-treated specimens. Then, the results of ultrasonic measurements were correlated with the microstructural investigations on the specimens.

Nodular iron was obtained using the process of the invention in one test involving a three hundred pound heat of cast iron. A comminuted mixture of 45% calcium ...
