Effect of Ta addition on mechanical properties of 7715D titanium alloy

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 s...

Summary: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.
