Generic Ti-46Al-8Ta Heat Treatments


  • The ingot was subjected to hot isostatic pressing (HIP) at a temperature of 1280°C and pressure of 190 MPa for 4 h to remove cast porosity.
    After HIP-ing the ingot was prepared for Jominy end quench test. Before quenching the Jominy sample was solution annealed at a temperature of 1360°C for 1 h in a dynamic argon atmosphere.
    The samples for tensile and compression testing were solution annealed at 1360°C for 1 h and air cooled to room temperature. This heat treatment was finalized by annealing at a temperature of 1360°C or 1260°C for 10 min followed by cooling to room temperature at a rate of 10°C/min.
