Abstract:The Ti6Al4V titanium matrix composite added with (0.36, 0.72, 1.45wt. %) La and (0.17, 0.34, 0.68wt. %) B, were successfully synthesized using common casting and hot forging technology. The microstructural characteristic and tensile properties of the heat-treated materials were investigated, with purticular emphasis on the effect of trace reinforcements. The phase analysis was identified by XRD. Optical microscopy (OM) and scanning electron microscopy (SEM) were used to observe the microstructure. Both room temperature and high temperature tensile properties were tested. The results showed that the addition of La and B plays an important role in the microstructure and mechanical properties of titanium matrix composite, tensile strength can be increased 148MPa, which can strengthen the matrix metal seriously.
