ABSTRACT:
A process for producing composite materials which comprises subjecting particles of a malleable matrix material, i.e., a metal or alloy or the components of a matrix alloy and particles of a reinforcing material such as a carbide or an oxide or an intermetallic to energetic mechanical milling under circumstances to insure the pulverulent nature of the mill charge so as to enfold matrix material around each of said reinforcing particles to provide a bond between the matrix material and the surface of the reinforcing particle. The process is exemplified by the use of aluminum alloy as the matrix material and silicon carbide as the reinforcing particles. Reinforcing particles are present in an amount of about 0.2 to about 30 volume percent of total matrix and reinforcing particles. The invention is also directed to the product of the process.
