Abstract

See full text

A method of making a reinforced metal alloy component, the method including introducing a reinforcing phase precursor into a bulk alloy that is selected from the group consisting of high-entropy alloys, aluminum-based alloys, magnesium-based alloys and combinations thereof. The precursor is converted to a reinforcing phase by exposing the bulk alloy and precursor to an elevated temperature during one or more of a subsequent heat treating step, squeeze casting shaping or semi-solid metal shaping.
