ABSTRACT

It has long been recognized that in theory a dispersion of particles in a metal matrix enhances the strength and heat resistance of materials. With the advent of mechanical alloying (Benjamin, 1970), it became possible to put the theory into practice by incorporating very fine particles in fairly uniform arrays into often oxidation-and corrosion-resistant metal matrices. The quality of the incorporation has resulted in commercial sale of a few of these systems. Inconel• alloys MA 754, MA956, and MA6000 are examples.
