Paper Title:
High Temperature Creep Behavior of In Situ TiC/Ni Composites
  Abstract

A 70 wt% TiC particulate reinforced Ni matrix composite was in-situ synthesized using self-propagating high-temperature synthesis and combined with pseudo heat isostatic pressing technique. The nearly spherical TiC particle reinforcements were uniformly distributed in the Ni matrix and most of the carbide grains were of 3-4 μm in diameter. Creep behavior of the TiC/Ni composites had been investigated in ambient atmosphere under constant load tensile tests. The stress exponent values of 7.69 and 6.62 were obtained at 923 K and 1023 K, respectively. The creep fracture should be initiated by a mixture of particle cracking, interface debonding and void nucleating, while interface debonding was dominant fracture at high temperature.
