Abstract
A light weight cast metal wheel having a disk-shaped wheel disk formed across an annular wheel rim and including a reinforcing layer of a metal matrix composite extending radially across the wheel disk. The reinforcing layer also can extend axially across a portion of the wheel rim. The metal matrix composite layer is formed by securing a preform formed from a reinforcing material within the wheel mold prior to casting the wheel. The use of a preform assures that the resulting reinforcing layer is uniform.
