| Abstract Scope |
Additive Manufacture offers reductions in cost and waste in the production of metallic components as well as the ability to create optimized topologies that are not achievable through conventional manufacturing. To date, few AM components have been qualified for high-consequence structural applications because of insufficient knowledge of the process/structure/property relationship. AM Ti64 has received attention because of the high material cost and the innate ability of AM to minimize material waste. The much higher cooling rates associated with AM result in distinct and metastable microstructures and, subsequently, distinct material properties compared to conventional components. AM Ti64 components are usually heat treated to drive the as-built microstructure closer to a wrought equivalent in microstructure and properties. We have collected diffraction data during heat-treating of AM Ti64 to monitor the microstructural evolution. The evolution of the phase fraction, texture, internal stress and dislocation density during heat treatment will be presented. |
