摘要

A process for the preparation of a metal matrix - nano composite work material (mmnc), comprising a metal matrix with embedded reinforcing nanoparticles, whereinfirst of all, both from pulverulent starting materials for the metal matrix as well as from pulverulent the matrix reinforcing nanoparticles a compact is produced, for the generation of the compact the pulverulent starting materials for the metal matrix and the reinforcing nanoparticles first mixed and subjected to a temperature treatment and finally a uniaxial be subjected to pressure, which leads to its consolidation,this compact then in a metallic melt, the at least the used for the compact contains the starting materials for the metal matrix is given, wherein the temperature of the melt to at least the solidus temperature of the alloy is adjusted, andthe melt with the compact is now exposed to an ultrasonic treatment,after obtaining a homogeneous melt is cooled for the purpose of crystallization, these.
