METHOD OF PREPARING IMPROVED HYPER-EUTECTIC ALLOYS AND COMPOSITES BASED THEREON

摘要

we describe a method of preparation of a hyper eutectic eutectic metal alloy and refined and strengthened and that is: melt the eutectic or hyper eutectic metal alloy, and particles of a refractory material, adding metal to metal matrix f ondue, mixing the molten alloy and the particles of the refractory mu00dfteriau.and take the resulting mixture under conditions resulting in the precipitation of intermetallic phase, at least one of the metallic matrix melt during solidification, and the products formed during the solidification process control set and includes lesdi the refractory particles.the particles added can be very small and serve only to further refine the intermetallic alloy, precipitation in the product, or they may be larger and serve as reinforcing particles in a composite consisting of the alloy. the products obtained are new.
