摘要：

The SHS reaction behaviors of the Cu-Ti-B4C System with various Cu content were investigated. Theoretical calculation of the adiabatic temperatures reveals that the reaction in the Cu-Ti-B4C system is self-sustainable for the presence of 0-72.22 wt.% Cu in the reactants without any preheat. With the increase of Cu content, the adiabatic temperatures, combustion temperatures and wave velocity decrease greatly, while the ignition time shows first a remarkable decrease and then an increase with the minimum value at 20 wt.% Cu. Moreover, with the increase of Cu content, the sizes of the TiC and TiB2 grains decrease considerably. (C) 2007 Elsevier B.V. All rights reserved.
