ABSTRACT:
Heterogeneous metal matrix composite (MMC), and preform for making same. The MMC has two distinct interpenetrating metal-containing regions one of which is rich in reinforcement particles, and the other of which is devoid of reinforcement particles. The particle-free region pervades the composite in the form of a three-dimensional, open-cell reticulum of randomly oriented ligaments interconnecting a plurality of nodes and defining a plurality of interconnected interstitial cells of varying size. To make the MMC, a preform comprising an open cell foam substrate infiltrated with reinforcement particles is filled with the matrix metal. In one embodiment, the substrate is a fugitive polymer foam which is removed prior to filling the preform with metal. In another embodiment, the substrate is a metal foam which remains with the preform and the MMC after filling with metal.
