Paper Title:
Research on the Microstructure and High Temperature Creep Behavior of In Situ TiC/Ni Composite
  Abstract

TiC/Ni composite material was synthesized by melt in-situ reaction from mixed Ti, C, Mo and Ni powders. Microstructure and phase composition of the composite were characterized by SEM and XRD. Creep behavior of the composite had been investigated under constant tensile stress, and the creep damage of the creep specimen was characterized by elastic modulus. The results show that the composite consists of nearly spherical TiC particle and Ni, the addition of Molybdenum has effect on refining the size of TiC particle; the mechanism of creep fracture is inter-granular fracture; relative variable curve of modulus resemble to creep curve, the method of elastic modulus is well to characterize the creep damage.
