Abstract:The TiB2 nanoparticles reinforced copper matrix composites were prepared by in-situ reaction which was controlled the content of reactant B2O3 and graphite. Microstructures of the in-situ TiB2/Cu nanoparticle composites were analyzed using XRD, EDS and TEM. The result shows that the in-situ synthesized TiB2 particles with a size of 50nm disperse in copper matrix and have asignificant reinforcement for the copper matrix.
