In this paper, Ti-1100 composite reinforced with TiB whiskers was fabricated using in situ technologies. Mechanical properties of the composite with randomly oriented and aligned TiB reinforcements are evaluated by tensile tests at 923 K, and the failure process of the composite is observed by SEM. Strengthening efficiency of the differently oriented reinforcement is calculated. The failure mechanism and strengthening efficiency of the TiB whiskers during tensile tests are investigated. The effect of the orientation of TiB whiskers on the failure mechanism and strengthening efficiency for the investigated composite is also discussed.
