Abstract
A metal matrix composite (MMC) may be formed with two or more portions each having different reinforcing particles that enhance strength, wear resistance, or both of their respective portions of the MMC. Selective placement of the different reinforcing particles may be achieved using magnetic members. For example, in some instances, forming an MMC may involve placing reinforcement materials within an infiltration chamber of a mold assembly, the reinforcement materials comprising magnetic reinforcing particles and non-magnetic reinforcing particles; positioning one or more magnetic members relative to the mold assembly to selectively locate the magnetic reinforcing particles within the infiltration chamber with respect to the non-magnetic reinforcing particles; and infiltrating the reinforcement materials with a binder material to form a hard composite.
