Research Project

High Temperature, Low Density Alloys Based in AlFeSi

The main goal of this project is to find an intermetallic compound based in AlFeSi to sustain high temperatures while remaining lightweight, as in car engine applications. The τ10 phase in the AlFeSi intermetallic exhibits excellent mechanical properties and corrosion resistance at high temperatures. However, this phase only exists in a very narrow composition range, which could limit its applications. Experimental techniques were used to stabilize the τ10 phase by expanding its phase boundaries using quaternary alloy additions. Elements such as titanium, manganese, nickel, and copper were added to the AlFeSi compound in varying compositions to test their solubility in the τ10 phase. Further mechanical testing, such as Knoop microhardness was completed to evaluate the presence of cracks under stress. A future endeavor includes processing a successful quaternary alloy as a powder to test for mechanical properties.
