METHOD FOR PRODUCING METAL OR ALLOY CASTING COMPOSITES REINFORCED WITH FIBROUS OR PARTICULATE MATERIALS

摘要

A framework template of non-reinforcing material is provided containing, distributed therein and bonded to the building constituents thereof, a reinforcing material such as particles, fibers or whiskers of high tenacity nitrides, carbides, borides, oxides and the like, this distribution being arranged according to some given pattern of orientation and packing density. The template is placed in a mould which is then filled with molten metal which solidifies by cooling. During casting, the constituents of the template may be destroyed by the heat, or they may dissolve in the metal, or they can remain embedded therein.
