摘要：

Cu-based composites reinforced with in-situ TiB2, particles were synthesized through the reaction among Cu, Ti and B4C using a 3-kW CO2 laser. The in-situ reaction resulted in the formation of TiB2 and non-stoichiometric TiC1-x particles in a Cu matrix. Some porosity was observed in the Cu-Ti-B4C system. However. with addition of Ni in the Cu-Ti-B4C system, almost full densed parts could be obtained due to improvement of wetting. (C) 2002 Elsevier Science B.V. All rights reserved.
