    摘要： A new alloy, obtained through a new method, which presents the mechanical and physical properties of the gray iron alloy, with a wide interface range of the CGI's tensile strength (TS). This new alloy, flake graphite based, is a High Performance Iron (HPI) alloy. Therefore, besides its high tensile strength, the HPI alloy presents excellent machinability, damping vibration, thermal conductivity, low shrink tendency and good microstructure stability (compatible with gray iron alloys). HPI's characteristics are obtained by a method that defines a specific interaction among five metallurgical fundaments: chemical analysis; oxidation of the liquid metal; nucleation of the liquid metal; eutectic solidification and eutectoidic solidification.

    摘要： A method for continuously providing pretreated molten iron for casting objects which solidify as compacted cast iron, in which inoculating agents are added immediately prior to casting, in exact quantities. In practicing the method, the ability of the fully treated cast iron to crystallize is measured and the result of this measurement is used for feedback control of the supply of inoculating agent, this supply being effected at the last possible stage of the treatment process, so as to optimize the amount of inoculating agent introduced to the system. Since the inoculating a gent will normally include FeSi, it will also fed back and used to increase or reduce the addition of agents for adjusting the carbon and/or silicon contents of the iron as necessary.
