Method to obtain a high resistance gray iron alloy for combustion engines and general casts
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.
The object of this application defines a new alloy which presents at the same time the mechanical and physical properties of the gray iron alloy, i.e., excellent machinability, damping vibration, thermal conductivity, low shrink tendency and good microstructure stability, together with a wide interface range of the CGI tensile strength.
