Fig. 11a shows that the minor addition of Si in Ti leads to the formation of Ti5Si3 second phase particles, due to the negligible solid solubility of Si in Ti at room temperature . The appearance of Ti5Si3 (HCP, a =0.7465 nm, c =0.5162 nm ) is further confirmed through TEM characterization (Fig. 11b). EBSD Kukuchi patterns of the alloy can be well indexed by the crystal structure of α-Ti.
