Abstract

High cycle fatigue (HCF) of a TiC particle reinforced titanium matrix composite has been tested at a frequency of 76 Hz and load ratios, R, of 0.06 and -1, respectively. The HCF strength for the composite at ambient temperature was found to be 594 MPa and 494 MPa, respectively. The results indicated that the HCF strength for the composite is comparable to those of Ti-6Al-4V and IMI834. The observed high tensile strength and high HCF strength is attributed its overlapping fine and thin plate-like α + β phase microstructure. The propagating region of the fatigue crack for the as-annealed composite was regular and wide, which contributed to its improved HCF strength and prolonged its fatigue crack propagation life.
