<p>The object of the present application is to define an alloy, which presents the mechanical and physical properties of the gray iron alloy, with a wide interface range of the CGI's tensile strength. 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). Said HPI's characteristics are obtained by a specific interaction among five metallurgical fundaments: chemical analysis; oxidation of the liquid metal; nucleation of the liquid metal; eutectic solidification and eutectoidic solidification.</p> |
