Abstract (en)

[origin: WO03045626A2] Graphitic cast iron of high mechanical strength, presenting a microstructure with adequate proportions of nodular graphite and adequate proportions of vermicular graphite to define a total amount of graphite in the range of 12-15 % in volume of the microstructure.
