Abstract

An interesting phenomenon that yielding was observed in the Ti matrix composites with above 4.10vol%TiC_p. To clarify the underlying nature, in-situ tensile test was performed, and results indicated that this was caused by cracking at the interface between the aggregated TiC_p and Ti matrix, which is quite different from the well-accepted viewpoint. Furthermore, fracture of stronger TiC_p prior to weaker TiB_w was also found during in-situ tensile test, and a fracture criterion was proposed from the viewpoint of load transfer.
