The flake-like shape of graphite in gray iron exerts a dominant influence on its mechanical properties. The graphite flakes act as stress raisers, which may prematurely cause localized plastic flow at low stresses and initiate fracture in the matrix at higher stresses. As a result, gray iron ex...

The modifying effect of aluminium on (a) the response of the low S and P containing iron to inoculation with foundry grade ferrosilicon and (b) the microstructural features and mechanical properties of the iron, have been studied. The various aspects studied include graphite morphology, matrix, ...
In order to understand the influence of microalloying additives on the graphitic morphology, mechanical and wear behaviour, a series of microalloyed cast iron melts were taken. The laboratory scale ingots made were characterised for microstructure, mechanical properties and wear behaviour. All the cast ...
Grey cast iron's thermal conductivity and mechanical properties depend on graphite flake morphology and length. Molybdenum is generally added to ferrous alloys to improve the mechanical properties as it forms carbides. However, molybdenum has two effects on the graphite flakes. A small quantity of Mo...
