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

摘要

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.

1. A method of making a reinforced metal alloy component, said method comprising:
introducing at least one reinforcing phase precursor into a bulk alloy that is selected from the group consisting of aluminum-based alloys, magnesium-based alloys, high-entropy alloys and combinations thereof; and forming said component as a composite of said bulk alloy and at least one reinforcing phase that is produced upon activation of said at least one reinforcing phase precursor by using either squeeze casting or semi-solid metal forming such that a linear dimension of said at least one reinforcing phase is in the nanometer to micrometer range.
