Abstract
A metal matrix composite material and associated methods are disclosed. In one example, the metal matrix composite material includes ceramic particles distributed in multiple phases. In selected examples, the metal matrix composite material is formed by a process including applying a rotational force and an axial force to a feedstock at an interface and plasticizing a portion of the feedstock at the interface.
Claims8
A metal matrix composite (MMC) friction extrudate comprising:
- a metal matrix, the metal matrix including;
- a first phase;
- a second phase different from the first phase;
- and
- wherein the metal matrix is continuous through the first phase and wherein the metal matrix is also continuous through the second phase;
- wherein the first phase and the second phase occur in respective regions aligned concentrically in an alternating manner.
