The 7715D titanium alloy added with 2.1％ Ta element,nominated as 2Ta,was successfully synthesized using common casting and hot-forging technology.Two kinds of heat treatments were adopted.The phase analysis was identified by XRD.The microstructures were observed by optical microscopy (OM) and scanning electron microscopy (SEM).Both room-temperature and high-temperature tensile properties were tested.The results show that the addition of Ta element plays an important role in the mechanical properties of 7715D titanium alloy,which strengths the alloy seriously.
