Method of making aluminum or magnesium based composite engine blocks or other parts with in-situ formed reinforced phases through squeeze casting or semi-solid metal forming and post heat treatment

Patent number: 9999921

Abstract: 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.
