Abstract

This invention disclosed a method for preparing the ultrafine intermetallic particles reinforced metal matrix composites (MMC). The particle size of ultrafine intermetallic particles is about 0.01˜5 μm. In this method, intermetallic particles and metal matrix were first ball milled together to get the mixed powder. Then, powders were cold-pressed then vacuum melting with metals to prepare the reinforced metal matrix composites materials. The intermetallic particles addition amount in this is 1˜30 wt %. This invention improve the dispersion properties of intermetallic particles while increase the particle/matrix interface strength. The ultrafine intermetallic particles reinforced MMC shows the very good performance with good ductility and strength.
